Start trying out different classes and methods of play so when you are able to prestige to 16 you have a more diverse arsenal and can level through those faster

to me, i play when i have time for, so not always, but i'm happy if ever reach 15...i'm totally against another raise of prestige, as i want to enjoy the end of prestige finally at some point...wanted to use the possibility to reset my stats at 10th prestige, but have to go to 15 again to be able to, how annoying...
