Democracy isn't suited for this community, I mean let's be real, this isn't a real community, the people who want balance and fairness here are seriously in the minority.
This is how a democracy could turn out:
The biggest clans pick their candidates, have all their members vote for them, have other clans vote for them in exchange for promising to buff what they mainly play, all sorts of deals are made in order to gain power and not in order to balance.
Candidates are in general picked class wise, let's say there are maybe a candidate from each class who got the vast majority of his classes support, then those candidates join together, agree to work as one and buff everyone who votes for them, so if for example cav and 2h join together then everyone else would glance, and if everyone joined against 2h (everyone else hates them) then 2h would probably get nerfed slightly more than they need to be.
And Riddaren your suggestion got major flaws as well.
