The problem is, that 50% = first 8-12 players who join and rush arena poll, from that 8 - 12 players 50 % is 4- 6 guys while everyone else haven't had chance to join server yet, i've come to notice if poll is made when all 40-50 players join - the outcome is far different. So i dont get the boasting that everyone wants to play arena when poll is made before by first few guys that join server, its like watching youtube video where first guy leaves dislike which counts as if everyone dislikes it for that moment.
To fix that would be fair to poll only once everyone who played previous map have finished loading the next map and then make a poll.
EDIT: It's obsurd to see poll gets accpeted by majority when 17 voted yes or no while server shows population of 30-40 guys
That's true. Maps which are polled as soon as a new map starts are more likely to pass. That being said, arena often passes even half way through a map when everyone is loaded in. I don't see any other maps doing this.
