He also said, twice, that the only reason to play new game + is to switch classes. It isn't. There are a good number of benefits to playing new game + aside from that. I provided a few of these - higher level weapons and abilities available earlier, the ability to max your character earlier and start with your optimal build to use it the entire game, a slightly easier path to getting insanity achievements, and so forth.

So while you are correct that he did ask about switching classes, and I didn't answer that question, there was another issue worth discussing in this post. New game + is worth playing for a lot of reasons, and switching classes isn't one of them.

I was wrong about the maximum level, however. Through careful hunting of medigel packs and never using medigel until all have been looted, it's possible to get to level 59 with an import. It still takes, so far as I know, new game plus to max things out, but by that point you're probably dumping points into skills you don't use anyway.
