Yeah as the title says, pretty much. I just picked up my first tank, Marauder, and the NPC in Hall of the Novice talks about Overpower as an AoE that's a cone in front of you, like I heard it used to be. It's a circle now. I know many other AoE's have been changed too, but I don't feel like checking them all if it's the same there. I have a tank to level with my time instead :P

Example I copied:
"Master of Shields: Overpower hits every bugger in a cone in front of ye─make sure yer positioned so ye don't miss anyone!"

Just a bit of outdated text that I thought it's nice for the devs to be made aware of ^^ I can imagine it's hard to keep track of all the mentions of different skills as they're adjusted in patches.
