They're dumb... and hilarious.

The latest changes to the Arms tree make the PvE rotation simply amazing... the first thing I thought when reading about it is the crazy cat-lady from the Simpsons (throwing cats at people screaming nonsense). Here's the rotation:

Charge
Slam
Overpower (if proc'd)
Execute (if proc'd)
Rend
MS
RUN AWAY
repeat

So basically, warriors will be running back and forth away and towards their opponents in a PvE setting... it's hilarious. If I can find a youtube video illustrating this nonsense, I'll post it. So far, I have seen some 3.5k parses against the Skull dummy by arms warriors doing this nonsense... when I get home I'll try and record some video of the parses.
