I was watching VCT then came across this thought. So in VCT your team can ban at least 1 map. You also get to pick your own. I think the banning goes first so your pick might be not be your best map. Unless the opponent bans their worst map instead of your best map. I believe that everybody has a bad map there's no way everybody can dominate every map. I've seen liquid ban bind and I think that's their worst map. In the recent game, I've seen drx ban fracture which is where zeta dominated liquid in the first half. Not sure if these are correct. Maybe some experienced players may give their opinions about my question.
