I have a few 99 lvls, and yes after reaching lvl 99 you do get another 'next lvl at 14,391,160', i think that lvl 100 does exist and that is it, when i got '100' range im sure i hit a bit better then at 99, but who really knows eh..? But if not then why is the next lvl there? you do not get another next lvl after passing the '100'
