It is real tedious coming back to the current epic quest system, especially after running in the event this weekend and seeing how enjoyable the high end game can be, I really noticed a big problem rearing its head again.
Its not the fact that the quality of the typical melee toon is low and completely unprepared for epic play. Or that they need not only a cleric always babysitting them. As well as at least one arcane immobilizing everything for them just to have a shot at hitting foes, let alone completion.
Its not the fact that the quality of the typical healers willing to join a pickup group has degraded to a horrendous level. So much so that they are incapable of healing unless party members stay tightly packed. I have actually found it better to use a hireling healer for many epic cases.
Its not the pathetically low drop rate of items. Essentially adding negative reinforcement to the desire to epic quest.
All of the above points could be addressed and a big problem would still remain. That problem is the way epic shards, scrolls, and seals are awarded to players. Now I know you addressed scroll drops. However, this did not solve the one big problem. Since all of these items are at least account sharable, more and more people are opting to take any of the former items that lands in their chest reward or ingredient bag.
This problem is especially true with the more and more common inexperienced player who usually has no idea what the crafting item actually crafts. Since these items are all so incredibly rare and incredibly hard to find, fewer and fewer people are willing to pass these items to fellow party members.
Now, as more experienced players see this happening (keep in mind the experienced players usually do the lions share of the work in epic questing), fewer of them are willing to join pugs. Interest in epic questing drops off as does interest in the game since your friends are not always available to play and a pug run would be nice to fill the time. Addressing this problem, imo, is even more important than addressing the drop rate of epic crafting materials.
One solution is to bind items to characters. This is better than nothing, but in general a poor solution since everyone, my self included, would much rather have account bound crafting material over character bound (or not bound at all). Therefore, I suggest you consider implementing the following.
1. When a scroll drops, the same scroll drops for all in the party.
2. When a seal drops in a chest, the same seal drops for all in the party.
3. When a shard drops in a chest, the same shard drops for all in the party.
This system was the system used in the event for gem drops. It is one main reason so many parties could form quickly often without regard for player skill levels or looting habits. No complaints occurred or party selections based on loot drop envy or jealousy. Perhaps it is because of the event this weekend and seeing how smooth the high end game could run, but I do not have a lot of tolerance now for folks who grab items that their questing toon obviously will never need. Especially in quests where I do the lions share of the work. I know others are getting fed up with this now all too common behavior too (it was the main reason the old scroll drop system really irritated people.
I know what many of you will suggest. Stop running pugs. Well, if there is no indication that this system will be addressed, then perhaps that is the only solution.
