I'm level 80 :s Flamethrower is hilarious on WvW cause it hits through walls/gates. And the Mortar skill is instant AoE carnage when defending. Combined with Rocket and Rifle Turrets, with the Tool Kit, and I can hold a gate single handed for a good hour.
Also, the final dungeon for story mode is the most boring and tedious piece of crap in the entire game. Holy shit there's like 50 different situations which are basically just brute force events. No thinking involved, just KILL EVERYTHING HURRRDURRRRR. Which is painful as fuck considering that one of the Champions (read as not even a mini-boss) took over 2 hours to kill because he kept regaining health off of minions he summoned. And that's not including fighting Zhaitan, or any of the other 3 dragons you have to fight. Plus the Mouth. And the 2 other Champions. And the 3 Towers of Orr. And the massive hordes of enemies. And the one hit kill Eyes of Orr. And the endless defending of dumbass NPCs. All for a rare hat.
Seriously, if I ever find the person who designed that dungeon, I will tear them a new asshole and cut off their genitalia and ram it so far up that new asshole that it will come out their mouth. I want the 5 hours that dungeon took back.
