Even if I have to pay tp upfront for it, I recently found out there’s a class rank limit of 7 and I SERIOUSLY do not feel like grinding all the way back to 70 minus all the founder’s benefits due to how vauge the class system is in telling you that there is a limit. I wanted to mix in Chronomancer with DPS but I went to Pyro by mistake thinking you had to rank the next classes to get to the next ones.
It should be possible to reset class ranks if skills and stats are re-settable as well.
