Are you a -blam!-in idiot, that should apply to you, does a boss in a gw2 dungeon glitch when someone leaves the party or loses connection? nope. Does this shit happen in WoW? nope. Everquest? Nope... Wildstar? NOPE! and the list can go on.... (Did you know gw2 handles disconnects by leaving you in the group and allowing you to get back into the instance when you get back in, on top of the dungeons not bugging) So yeah, I've played many games that require online connections, and your sorry ass never did from the looks of it
