I not going to defend them for delaying 6v6 IB(i think is bullshit) but using the whole "they already had 6v6 in D1" as the reason for call them on their bullshit seems wrong to me. D1 6v6 is different from D2 6v6. D2 have a whole different scoring system and mechanics attached to it. If the bug they found is score related, they can't use D1 6v6 as base to help them figure out and fix a score related bug in D2.
