I believe if you freeze your exp gain at level 49 you could potentially do everything without being overpowered, if that's something you enjoy. If you just want to play single-player and quest all the time, this could be an option.
I haven't tried it yet myself but on my next alt, I will test it out for sure. Has anyone else tried it yet?
