To me a good thing would be a WoW drop style. (But, in a different note, WoW has a lot to give to this game in terms of looting a pvp, but that's another story.
As Lyndisty said, a "guaranteed" item would be great BUT (and it's a BIG BUT) it woud be even better if it was from a common boss drop instead of from the goodie bags.
So people can actually roll (and see when and if something that you want is dropped) for the item OR (even better) clan mates can even use the master looter (otherwise pretty much useless... kinda useful only IF you manage to get the optional achevement).
That would be great.
Even better would be adding few more items to the "Sets" (even new sets would be great as well, maybe when you will add new STF..)
OR, and it's a big "OR" you let buy Ml XII item with... 15 EDC? or something like that.
