I read the first 19 pages of this thread but couldn't keep going. Most of the people are saying very similar things anyways. I will post my thoughts below:
TL;DR = This should not go live (ever, but definitely delay the patch)
Longer version below -
Issue #1 - Crafting should not use BTC or BTA items
I have a deep hatred for BTC and BTA accounts. They make the game economy too boring and there is less incentive to farm quests (compare Gianthold era to recent updates, everything is bound these days. Unless you need something, you don't run the quests at cap). With that aside (and that's a huge thing for me to put aside) crafting really cannot use bound items. On any one account, it only makes sense to have one crafter. It would be too painful to have multiple crafters and it just doesn't work out since you need to pool all your items anyways. If you have a BTC item on an alt that is not a crafter... out of luck! This alone should eliminate the need for BTC items but there are more reasons. BTC items are a pain when they drop in chests, since you can't buy them you have to be there when they drop. If a BTC item drops for someone else, there is still a chance they dont need it so there is a big incentive for them to pass it to you. If ANY BTC items are used in crafting, everyone will loot what they get. It does not matter if the item is needed for crafting or not, it MIGHT be in the future. We already see this with raid loot. People don't need an item but they loot it anyways 'in case they make it epic' or 'in case i TR'. Chattering ring for a greater halfling bane is so silly I just laugh but it doesn't even have to be that huge, it could be the worst BTC item and still have the same effect because 'it COULD be used for crafting in the future'. Now you might say "ok fair enough, let's only use BTA items". Well that has an even worst flaw. We already have people looting random useless Epic Seals and Shards just because they are BTA and they might, someday, possibly, roll an alt that could use it. There is no incentive to pass any epic piece unless you have 5 of them or have a friend in the party. It is also really bad for crafting because if you want to craft an unbound item, YOU have to find the item. You cannot sell your services to someone else and have them provide the ingredients.
Issue #2 - Crafting should not use Raid Items (incl. +3/4 tomes)
I don't even have to explain this one, guys. I'm not going to ask for anyone to get fired but please, if you made this decision and are reading this, just think about it for a second. If you know the person who made this decision, please have a friendly talk with them. The fact that this is even considered is really frightening. Raid loot items are by nature rare. Not only are they BTC (see Issue #1 above) but you can only get a CHANCE at having one every 3 days. Even if the item you want drops in the party, there are 11 other people that probably want it too. People are already greedy, people already take raid loot just because it's called "raid loot" (I have seen a drow take the Titanic Docent because it was 'his raid loot') but this makes it so much worse. Now there are three reasons to take raid loot: You need it, you greed it, you destroy it for crafting. Seriously? You have 11 other people in your party eyeing the raid loot you can't use but you will take it anyways and break it down? Come on... This is even worse for tomes because TECHNICALLY any character can already use any tome and many people take tomes which would be MUCH more useful to others, this makes it even worse. Like I said, I should not have to explain this one, I think it's self explanatory
Issue #3 - Crafting should not REQUIRE DDO store items
Crafting cannot be dependent on DDO store items, even things like Astral Diamonds which do, every time the moon is aligned with the stars, drop in quests. I understand the business requirement here, there is a huge interest in including DDO store items in game mechanics to boost revenue, that's a good thing for the game in general. However, this should be restricted to recipe chance boosters, crafting xp pots etc... Things that are really nice but only avoid some REASONABLE grind (ie you can do the same without but it will take you longer, but reasonably longer). Leave the DDO store for what it should be, meta-game. Sure it is a great revenue stream when you include things that shouldnt be there (+2 tomes...) and I really disagree with that but it's not gamebreaking, i don't HAVE to go to the store to play the game itself (as opposed to having kickass hair or good looking armor). This is discouraging because those that want to craft will HAVE to use the store. My guess is anything bought from the store will be bound, which leads us to Issue #1, you cant craft anything unbound for someone ELSE without hitting the DDO store yourself, many will not be able to do this. Leave ingredients out of the recipies, use the store to help people level faster, succeed more etc...
Issue #4 - Major changes to the game like this should not go live on Lamannia after it is 'too late' to undo
I will keep this one short because we say this every time but the devs never listen. Either show something on Lamannia and have time to change/cancel/fix it or do not show it at all. It is frustrating to see broken stuff but it is even worse to see it coming and not see anything being done about it. Trust us, we wont mind if you cancel this update, even with the other nice stuff bundled into it. You can release this now and undo the crafting changes later but people will still thing 'they might try X again, I'm hording my leuts!'
Non-issue #1 - Using ingredients, collectables and unbound named loot is a GOOD thing
Using small/medium/large devil scales for lesser/-/greater outsider banes? Great! Using tasty ham for animal bane? Fun! Using Yark!Yark! Prayer Beads for Kobold bane? Kobold Never Forget! These things are good, they add flavor to crafting but also appropriately increase crafting costs without hurting the crafter. Crafters can still get ingredients from loot/trade/AH which boosts the economy or have people bring their own ingredients and supply the crafting level chances for a fee. Heck, if you want to go for some old, never-used named items like Rusted Shamshir and the like, go ahead! It breathes new life into these items, just make sure they are NOT bound items (Issue #1) and aren't items currently useful or sought-after. Kardin's Eye for crafting would be silly but Royal Scimitar? Meh, sure! It will make people run PoP again! Many will not want to grind old quests but that's fine as long as the items are unbound! The DDO economy is tanking, there are very few things worth buyin/selling these days due to excessive BTC/BTA loot, this shakes things up a bit.

Anyways, for what it's worth, those are my thoughts. As many people have said, if anything this tells us (ONCE AGAIN) that there is an insane gap between what the DEVs understand in this game and reality. Chattering Ring for Greater Halfling Bane? ... Seriously? *MegaFacePalm*
