That is interesting. Can you share why you feel like that is? To me, things like
Striking the Anvil makes a big difference. I never look at numbers, and the playstyle feels fluid, dynamic and it never grows stale due to mentioned procc-based game style.
If I had looked at numbers and seen myself keeping up a DoT and my other choices mattering less, then yeah, maybe. But I only look and feel what I actually
do and that makes it one of the most fun and engaging playstyles. I
wanted to dislike it, but I didn't.
The one problem for me with Arms, is the solo game play. Being a DoT-spec rather than "2H smash" (which the play style implies), it makes questing for the Alliance Campaign a hassle. I am at 463 iLevel now and I don't... one-shot the things I'm expecting to one-shot. I think I am a Retribution Paladin with Templar's Verdict, but I am an Unholy DK with a setup-and-rot, which belies how it actually feels to play it.
Fury, to me, is far more of a snooze fest since it pretends to be a dynamic and fluid playstyle, but the rotation feels rather static to me. At least in the build I'd prefer having, since I prefer playstyle over numerical superiority. I also wanted to love Destruction, but it's a very Infernal-centric playstyle, and I hate using cooldowns.
