I've noticed many will try getting a vote to abandon going, quit, try getting someone else in the party kicked (then quit if there is another wipe or things don't go smoothly for them) as soon there is a wipe, but most of my first clears in extreme battles have come from dedicated players voting against abandoning and trying until we win. When we cleared extreme Thornmarch, we finished the boss within a minute of the time running out. It was a very rewarding victory, despite the difficulty in attaining it.

Personally it makes me more determined to keep trying to win when someone is new to a battle and having a hard time clearing it. Best thing you can do is not become like those short tempered people and don't side with those who start pinning blame on people as soon as there is a wipe. Have a positive attitude and shine as an example of a better type player. Vote no to any abandon and kick votes, unless someone is disconnected or purposely causing problems for the group.
