While for the most part the people in this game are cool every once in a while I run into a thoroughly unpleasant person while in a dungeon or raid. For whatever reason, these sorts of people seem to take delight in putting others down or just being generally rude.

I would deeply appreciate it if the dev team could rework the ignore feature so it works while in dungeons and raids. Being able to immediately filter someone out if they're obviously going to be a jerk would make such dungeon run experiences much more enjoyable.

A bonus would be if using ignore on a person prevent you from being grouped with them again. Last I checked WoW has this built into their ignore function and it's a very nice touch.
