Mod the experience required per level / max level cap?

do the problems start already at 100+1 ? or is there a ‘safe’ range that doesnt trigger unwanted side effects like no enemy spawning in ultimate? <- yep, they do (see below)

edit:
see also here:

and i think if logic isnt luring, editing the templates default values should solve that (instead of haxxing the game.exe - or asking GI Author to add a slider for maxlevel default value:) )
