How in RoS are you supposed to complete lets say a five piece item set.
A few notes:
1) Smart drop doesn't take into account your current gear when dropping items
2) No AH
3) No trading except with party members for 2hrs only
Looking at the now long and expansive list of legendaries and set items, it seems that it will be nigh impossible to complete item sets.
You would either need to find the pieces yourself, which is probably astronomically difficult or be lucky enough to be in game with someone who gets a piece you need...tells you they got it.....and is willing to give it to you.
I understand that itemsets are powerful and should not be able to be acquired to quickly, but with BoA and many other commodities (gold, crafting mats, gems) being locked down, it makes it somewhat difficult.
Please consider allowing a one or two time trade rather then the two hours. Also allow items to be traded within clans, to promote chatacter diversity and cooperation with in clans.
