I am Arms specced and at the moment the best gear I have is the crafted PvP set (I have not done any dungeons yet).
I find some of the final elite bosses from the Golden Lotus dailies quite difficult to kill. Some are easier than others, but today I just could not kill Cracklefang. His AoE thingie takes about half my HP away every time it catches me.
I also find it impossible to kill most of the rares out in the world.
Is anybody else having problems with elites as Arms specced warriors or do I just not press enough buttons? I am considering going Prot, but then it would take me an hour longer to finish the dailies.
