Rogue; -Thief's Vision doesn't work with the aa's to extend it's duration. - Not really a "bug" but probably more of a case of really poor design. Phantom Assassin (rogue pet) is taunting off tanks, which makes it hard to use on raids (if at all, not worth the dps if it's messing up aggro) and obviously useless when solo (unless you enjoy watching your healer merc get killed). Rogue's have enough de-aggro abilities available that this is kinda unnecessary in it's current form and mostly just a gimmick. (Possible Solution--) Should act more like a jolt for the rogue, and shouldn't taunt. This can be accomplished by simply adding a 1 time jolt onto the disc, as the disc is pressed it jolts the mob, then does it's limited dmg and nothing else. Still confused why melee got pets in the first place but if we're gonna live with these dopey things at least make them useful.
Yes, please fix Phantom Assassin's aggro. Rogues are not in great danger of over-aggroing on raids anyway, but that pet does more harm than good. Currently, banning it from raids saves a whole lot of headache.
While doing the House of Thex group mission if people use short duration pets it will not give you the achievement -Use Not My Bones.
