It's optional, stop [censored]ing.
So is fast travel, but people still do it.
Personally, I don't care one way or the other. Using my own leveling mod, and at 134 hrs gameplay I'm at level 28. If I'm lucky I'll make two maybe three more levels before I retire this character.
IMO raising the level cap to 50 would break the balance of the game...unless they (devs.) rework the distribution of skill points and perks to say maybe every third level. Doubtful that'll happen though, people seem to enjoy being Godlike while playing video games...myself, I like having a little vulnerability ion my character; knowing that there is something/someone more badass than you out there let's you know just where you stand in the world.
