i dont know how GPG uses clans,but i do know about the clan system in WC3, which i really dislike.
i hate the idea of having "shamans" or "chieftains" as i find that this promotes superiority, when this is infact a "team" game, kicking a player from the clan should be agreed upon by a large % of the people in the clan, as with joining a player to the clan.
i also wonder about clan matches when demigod has alot of heros, will their be a banning and picking system like in dota?
or will you still just pick your hero in the game lobby and continuously change hero to counter others until the host decides to click the start button?
