Let me provide you all with some context. I queued into leveling roulette as my level 69 ninja and got into the level 69 dungeon. We started progressing and killing and just before the first boss the tank runs back to the beginning and and sits down without saying a word, we tried to be patient assuming maybe it was an emergency, but he never came back. After waiting 15 minutes we finally decided we needed to boot him or we would not finish the dungeon in time. Later after replenishing our party we moved forward and just before the second boss our healer reaches level 70. As soon as they reached level 70 they left the dungeon only to leave us once again looking for another hard to find important role so we can finish the dungeon. I myself try not to be so critical about everything, however i wanted to get other peoples opinions on this as i have started seeing this happen a lot more often and i do kind of feel that its rude behavior and not right to do that sort of thing to other people who are trying to get things done because they don't have as much time to play the game as others.. I feel as though when you click that commence button on a duty you should be committed to it unless something important comes up. Not intentionally leave halfway through because you capped and don't feel like finishing the run. Being lucky we managed to get a healer and tank to finish it, but i feel that some people aren't that lucky and have to end up with a botched run simply because the person who left was lazy or something. Now don't get me wrong, this is less of a rant and more of a post to find out where other people stand on this. I welcome everyone's opinions whether i agree or disagree with them.
