+ 1000 x 56 (9x5)² for the 1v1 Arena with a ranking :p
I agree BG would never pop if we had tiers. Yes, it's annoying to have low geared people but it's 100x more annoying for them tbh.
About the reason why they are low geared, it doesn't really matter, it's a game so what can you expect ? You can't force somebody to gear he is there to play, so if he is not it just mean that he doesn't want to or can't. Both are legitimate. It's more annoying when they are AFK. But the random chance to get this kind of player is equal in both side so I guess it make it "fair" kind of

.
I personally prefer having unbalanced BGs than waiting 1h in the Queue.
