If that is the case then, by your logic, they need to ban people for a lot of things. Such as: Using multiple Marks of Death to kill dragons fast, stacking other abilities that shoudn't stack but do. Double tapping abilities so you shoot multiple before cooldown. It makes no sense, we do the same thiing over and over and over again in this game, I love the game but it is extremely repetitive. At least this, for the past couple weeks, somewhat broke the monotony of the game. I for one ended up in quite a few of these lobbies, I made up alot of xp that I lost from crashes and other bugs like that. Banning wont help it, only kill the game
Perhaps they need to punish people for a lot of things. Not necessarily ban, but punish. Double tapping abilities were largely fixed, and even if people exploited them in the past, it doesn't justify that another exploit can be considered acceptable today.
Besides, if it ever comes down to banning, it shouldn't affect those who have unintentionally landed in glitched lobbies nor those who have glitched their lobbies by accident, which would include the majority - if not all the playerbase.
However, banning a few punks who have been abusing the glitch on purpose for two a half week won't kill the game at all. It would, if anything, send a message that Bioware is a serious gaming company that it looks after their playerbase.
