I definitely understand your point about warriors not being able to solo a boss. Keep in mind sorcerers cannot either as we are too squishy and die from one hit. Rogues seem to have a big advantage when it comes to PvE.

On the other hand, they have to be very careful with any changes they make as it could affect PvP as well. Right now I feel like PvP is pretty balanced. But that could change very easily with any big changes being made. For example, it's impossible for a sorcerer to beat a warrior in PvP without stunning him repeatedly. Correct me if I'm wrong, but doesn't Juggernaut cause immunity to stuns? If the cooldown was lowered, that would have a huge impact on PvP.

I'm not saying they shouldn't make changes, but they have to be very careful and make the changes pretty even.
