I have to admit there's a part of me that wants some form of trading besides what we have now, but it does seem that just about every idea could be exploited by bots/farmers. But as someone that was playing a lot both before and after patch 2.0 dropped, I can say this; there's one FUCKING AMAZING (undocumented, not really talked about much) new hidden feature of the patch.... and it's this: Suddenly, as of the day the patch dropped, I immediately stopped getting fucking bombarded with 20+ friend requests from "pvpbank#xxxx" every goddamn time I log on. And so for that, I am totally fine with BOA.
I was never a huge fan of D2's trading to be honest, because SOJs became sort of the defacto currency, and even when you started non-stop running for loot they could be extremely hard to find. I probably played over 1000 hours of D2, and granted I wasn't loot running most of that time, but in all that, I think I got 1 or maybe 2 legit SOJ drops and none ever from Gheed. RNG gonna RNG. I'm satisfied with the D3 Loot 2.0 drop rate, I have a ton of fun with the game, and if they can keep the third party resellers out, I'm fine with it.
