Here's the kicker in all of this - if it is boring not being able to improve your player, on a team you aren't affiliated with in any way, why wouldn't you get Karnage to help out Stockholm and maybe win them a game, since he has the team average in tpe anyway basically? You get to see him improve and that fixes your 'boring' problem.
Well, obviously you wouldn't want to for a couple of reasons: a) you don't get the extra TPE benefits so you can't start Karnages VHL career at like 350TPE or something absurd and b ) Tanking = better chance at lottery which is best for your team.
I just see this whole suggestion as trivial.
