I firmly believe people would still PL, then just go blow through content without any effort. People (in general terms) always take the easiest or fastest path. Unless mid-level crap is capped, people will just roll through it at 50. Yes, some people will do it on 30s when its available, and ya... you can help on ur 50!.... I still support level caps to keep mid-game content amusing if/when they add some.
