2 Map veto isnt even that much of an advantage in a bo5, 5 maps will be played, you get to ban the lower bracket team best map and your worst map, but you would be able to ban their best map anyway if you didn't have the advantage, and if your best/worst map and the lower bracket team best/worst map overlaps then its useless too, also i can argue that playing more games on stage actually gives you an advantage, at Tokyo for instance Loud went straight to playoffs and then lost to EG and EDG both group stage teams that played matches on stage before, and Loud players said on the interview that they felt like they went to these matches "cold".
