Thanks a lot for the help. I did some reseach as well, tinkering with the json file is most likley agains the terms of service so i decided not to try around with that.
Nope if that would the case i would have cut the level system and would been good to go. Still I appreciate the help!
The solution i came up with is reorganizing the entire skill base and optimizing it a lot better and tight. I didnt do that before since i had no idea that limit existed or else i had planned with that in mind.
I already started testing around and it seems like it will fit, it is just a lot of work, since i need to manually fix each skill position and then play through the entire game again to see if everything works like it should.
I also needed to give each enemy less support skills to make more space but i at least can say that everything should fit once I am done, including space for all future tf forms and party members^^
Its just a very boring and long work but its not the end of the game luckely!
