I'm currently 2300, so not great but pretty up there. Arms is fine, It's demise is greatly exageratted, it's not the best but it's certainly viable with the right comp, WLS/Turbo are both very strong. Abusing sharpened blade properly, and hitting very IMPORTANT banners against certain comps is necessary. You will be doing a lot of talent changes based on the comps you play against and you will need very good communication with your team.

I've been seeing a lot of prot warriors but haven't lost to a prot team yet, i fail to see how they're better then arms, even more so after the nerf they took. Arms isn't about max damage anymore, it has a good amount of utility that must be used effectively.

But it does have enough damage to put in work, I'm currently running WLS and just abusing my utility and countering classes defensives with a sharpened blade into CC on the healer when it ends will win you many games.

Shadow priest disperse? Shapened blade, cooridinate a CC chain on the healer, finish while the lock continues to rot the entire world. To be fair i'm playing with a very very strong warlock so maybe that's why i'm having such success.
