The problem with any sort of post-cap exp system is the devs themselves are dead set (currently) against the idea due to Balance™. Add in players who cry "illusion of choice" and you end up with a nonstarter. I'd love to see some manner of merit point system that adds in small boosts to classes because growth is fun, and yes a meta will always exist because number crunchers will always exist and say "you do it this way or you're trash", but is The Best of The Best actually required for anything outside of world firsts or speed kills? And why should we let interesting systems wither on the vine because we're afraid that some people will be a bit meaner than usual (gee I feel like I'm back in a parser thread).
