i hope they have something like that or at least raise the level cap a little bit higher
There is no level cap, if you are at 81 it is because you have 100 in everything.
The new perk trees do not affect your level.
Why would you even want it raised? At 81 you can destroy anything easily.
The game was specifically designed where you cannot experience everything in one playthrough, make two or three characters covering the different perk trees.
