90% of the player base in-game does not come on the forum and are mis-informed. a simple look in global chat shows that
the only true poll a dev could do is a in-game one running for a week then you reach everyone (99%)
Polls on forums are silly snapshots of the current tough of the current forum visitors, not the game player base. only thing a forum is good for is for the collection of information and creating awareness of game-play issue's what then would require a in-game-poll to see if its really a issue or a vocal group not being happy.
