I honestly don't know what I'm going to play in Legion. I took another stab at arms on the PvP server yesterday (I'm primarily a PvP'er), going in open-minded in an attempt to try see past all the problems. I couldn't even stomach more than 1 or 2 battlegrounds. We have nothing, except damage. And that damage is useless when you're dead the whole time. The massive reliance on having a pocket healer is so absurd its laughable. I spent most of the games trying to stick with my group as best I could, and even then most teams will pick out the glass cannon arms and clear them off quickly.
Multiple fights I was thinking, I could really use a heal, time to enraged rege........ oh
I guess I can go defensive stance, buuuut there goes all my damage. Maybe I just got unlucky in the bg's I played, but we need
something to help us survive better. Most fights I pop my 1 shot macro, get a bit of burst out, then people focus me and I die in a couple of globals, especially if I don't have my fear/shockwave up. And don't even attempt to try 1v1 or 1v2, there is not a hope in hell you'll come out of that the winner. I never thought I'd say this but at this point WoD arms is 10x better than Legion arms (for PvP, before you all shout at me), not only in how good the spec, but also how enjoyable it is.
