Or at least require a 75% (or higher) "Yes" vote to go through.
Why should half of the 24-man alliance be able to kick the other half out, thus making us wait 20+ minutes for another queue, on top of the 30+ minutes we spent in the raid anyways? If people don't like how things are going, they can leave, and be replaced.
With how people are still so bad at Weeping City, at least half of the groups I go in get Vote Abandoned, when people should of just left.
And in my experience, the people bringing up the Vote Abandon (or leaving because it didn't pass) are usually the problem, anyways.
