I hope there is a very strong 2v2 or 3v3 system, It would make sense I am sure this one will not be a traditional tournament but more of a fight to survive thing. Meaning travelling in groups would be pretty normal.
Not to mention from a game perspective the more variables in a match the less likely one character will be op. Say Character A is Godlike but is hard countered to Character C, so it's fine they have a strong character but you have a counter and your strong character. It adds a lot of strategy to the games.
I still love the 1v1 game modes but it seems they are just getting to a point where there will always be just a select few in the top tier or tournament tier.
