So you are saying those people who doesn't even participate in the current season that they voted for, deserves more for a guru spot more than the ones who compete? They knows the best arena format than the players who played in it? How would they know what's best for arena, if they haven't even compete in the current one? They just know? Those forever 100 elo solo game players just know what's the best arena format right? Surely they didn't play the game, because they love it so much, and all knowing, they don't even bother to compete in arena, but hey let their infinite wisdom decide how other player compete in arena.
What about having the top 100 elo player as the gurus in the community then? Are you going to say: "Oh they only play the game at the highest level, they don't deserve to be a guru, they don't know the game."
