The higher ranked players are playing all 3 mods and have way higher elo on their top one, your flat elo in bigshitdojo wont be helping and you're a good few points off the current "average" for them.
At the moment you'd be needing a 1605->1610 average or better across all 3 to break into the top 20, and around 1615 average to hit the top 10.
Does this really make any sense that ABD is purely the deciding mod for some reason? still pretty confused.
