I agree with you on much of this, but I hold no ill will toward those that used the 125,000 construct/deconstruct method. they were following the rules and were very public in these forums about how it worked.
I didn't use the so-called "RUCrazy method" because to me it did seem truly crazy. I can't and don't want to imagine crafting 125,000 shards for immediate deconstruction. I'm sure some people did it, but frankly it was only "efficient" from an essence perspective (did't use a lot of essences) but it would have consumed lots and lots of time (remember there was a timer on deconstruction prior to the previous update - the elimination of the timer on deconstruction would have changed this, hence the need to do away with xp from shard decon).
I leveled to 93 / 93 / 93 before the shut down without using that method. I did this by crafting whatever shard yielded the most xp for the resources consumed. I spent a lot of platinum on cheap +5 items and greater essences from the AH. I hit a brick wall around the 40's until unbound crafting widened and deepend the xp pool. I then crafted unbound shards for my guildies and they started sharing essences in order to help me along. I also took risks with recipes that might fail in order to maximize xp. I used a few store crafting boosters. I tested the whole system.
In short, I worked at this. I was careful with my resources, but took reasonable risks to maximize xp. This was not an abuse of the system but it still allowed me to (almost) max out.
I will also assert that leveling is still very possible (and efficient) using unbound recipes. I am still getting really good xp (150+) from many unbound shards that consume modest resources. For example, recipes with collectables tend to be very resource efficient, so I consolidated all of my collectables on my crafter.
EDIT: i think, what I took issue with was the theme that anyone with a high crafting level must have abused the system to get there. I got there through focused effort and at high expense in time and resources.
