I don't think BOAs are OP. If he thinks PVP with BOAs was bad, he should have seen it before the XP-OFF feature. BIS gear was much better than BOA and you had the bracket campers in guilds called "Dun Wurry Im Pro" 2 shotting everyone then bragging about it. I never see BOA players brag.
So much ridiculous hyperbole and misinformation in this post, I don't even know where to begin. It would probably be more productive to just down-rate it as trolling, but... /sigh
1. BoAs are BiS in quite a few slots, hence the reason so many xp-off twinks still wear them. Hint: If their xp is off... they aren't wearing them for the xp gain.
2. Just to reiterate... the very idea that "BIS gear was much better than BOA" is absolutely false and ridiculous. Period. Utterly ridiculous. The Bloodied Arcanite Reaper is better even at 69 than the best quest blue available (Axe of Frozen Death) by a very large margin.
3. Every low-level BG I've done for the past 4-5 months has had some random Lx7 or x8 in full BoAs laughing in BG chat about what a "beast" they are and informing everyone of their greatness every time they kill another undergeared opponent.
In short... yeah, I don't think a post could be as wrong as yours without being an intentional attempt at trolling.
