What balance changes do you want in the next update?
Mine is an obvious one, but Moonknight. His voiceline should take place just before he uses his ult, not after - and damage should be reduced a tad - but primarily the voiceline cue needs to be changed.
I also think Mr. Fantastic could use a bit of a buff to his damage output. Hes supposed to be a duelist and less of a vanguard. I get hes kind of a hybrid but he should be outputting more damage imo.
