How about you leave a wheel of fate that allows players to obtain extra points at the allocation screen. I mean cultivation protagonists have more abilities cimpared to others.
I think you should also develop some stronger versions of the merididan purification technics. In my opinion it is the best technique, but the output becomes so bad after the 5th stage, that I had to help with many qi gathering pills in order to reach the 6th stage.
I struggel the most with the time you need to get to the breakthrough. You could also try to decrease the strength of the bottlenecks. I needed to reach the 6th stage like 7 qi gathering pills.😅
