What level cap are you on about? the level 11 perk point cap or the level 42 hardcap? also if you have hit level 11 check their background some like farmhand is good to switch out for a sellsword or something that gets better start stats. for a level 11 hedgeknight or sellsword with good stars and stats are monster and to remove the cap would then void their higher tier backgrounds. not to say that when/ if we get the ability to mod game files there will probably be a mod for you.
