No don't uncap it. TTC is already giving such a limited amount of TPE for veterans. Milestones are essentially like a pension - you put in the work earlier and you get a little leeway on PTs later on. Separating it from PTs WILL cause some TPE inflation. We created a new update scale to combat inflation... let's not once again create inflation because we can't max out our players and people are sad about it or because it takes a little time to be a top player.
