the game will be 6yrs old tomr, there hasn't been a single year when mara were ever a bad class.
they always been Op or at worst good class.
they are not that difficult, rotation will become muscle memory in few dozen matches. kazillion dcds ensure they survive through tons of damage while melting everything. only class that can 1vs1 sniper/mercs and win.
but don't worry mara/sent fanboy your class will never be nerfed, bw clearly favors it.
