ok the issuse is that i have no idea of what class i shud pick do you guys have any speciffic one thats good for beginners?

it all depends on what you want out of this experience. Do you want more energy based attacks or more hand to hand fighting attacks? or do you want both? do you want a sword? do you want to be a majin and kill lots of mobs at once? do you want to be a namek and heal people? do you want to be a namek and kick peoples butts? its all about what you want. each class speaks for itself so go for it. As far as beginners go any class is really self explanatory and youll learn it as you go
