I'd like to report a glitch too: on a non-warrior character I was able to mine nodes in Orr and actually killed risen. I would walk up to risen farmers, see the purple light at the end of their shovels, and dodge, which put their big knockback on cooldown. I also do the same thing to knights in Twilight Arbor, except drop caltrops and then draw aggro, watch the stance and quick hammer spin animation before they leap, and dodge, then my party would focus down the target with the red over his head. Thieves aren't meant to be tanks who can undo aggro on demand while curing conditions in stealth so something is seriously wrong here! I was a thief in a dungeon, another exploit, should know not to go outside of WvW and only use a 30 power/30 precision/10 trickery build to play as intended! A thief that doesn't die in one or two hits in a dungeon? Something is seriously wrong here! Anet may as well remove our acrobatics and shadow arts trees ASAP!
Then, I traveled to Orr, swam, and shadow refuged around an ore node to reset the mobs' aggro just to get it.
And in WvW I was on my ele and managed not to die because of its build and timing of magnetic aura. Magnetic aura is easy to abuse and should be fixed ASAP before people keep dagger throwing/kill shotting/whatever into it getting themselves downed!
