the breakaway doesnt work alot on sonias brain dead combo that does 50% of your health with only 1 offensive meter.... It is wonky sometimes. I miss the rolls too but I also think i just suck at the rolls and mis-time them.
As for the special meter, go in the tutorial because some meters have to be amplified after the special move and some are pressed with the special move.
I miss kombo breakers a lot.
Rolls are useless, imo. OK, they disrupt the combo, but don't push away your opponent.
The roll is good to roll towards them and punish a combo or use fatal blow. But a back dash can prevent both rolls and both wakeups then a punish follows right after. Sub zero and kollector can combo you all day because you cannot use breakaway on them and I think that's absolute trash that kollector can endlessly combo you then attempt a reset. I still whoop his ass but its still dumb gameplay .
