Bound stuff makes thngs more fun and you get happier when you finish an item. Nowdays when you get that EE thing you really needed you just say oh well... that was not the feeling of completing a claw set or chrono ser or a chaosblade before u14. So my point is to make things bound again, while not hurting the majority of players who prefr the easy wasy:
Epic normal items stay like they are
Epic hard items drop ready like nowdays, but bta and btc on equip
Epic elite items need shard/seal/scroll (no blank) - shards and seals bta and scrolls unbound. Also when you finish the item btc. Shards drop only in the end quest of the pack. Note that for these iems that does not require a raid you dont need to have the base item because it would be silly as it drops on end reward.
Raid items follow the old rules: shard/seal/scroll/blank - shards are bta and drop in the raid on epic. Seals are bta and drop any quest/raid of the pack. The scrol drop from any mosnters in any quest/raid of the pack. The blank items drop both on heroic or epic raid.
