I could argue with that honestly I think its more suitable if it's only the first and the last chorus while the rest can be replaced with buzz sliders to keep it simple just in general to avoid overly complex shaped sliders too many times ifykwim? hopefully that makes sense but if it doesn't then you're probably right because I'm very much inexperienced in all of this
I'm assuming you meant "overall difficulty"? I increased that but if you mean the general difficulty as in SR then I think it isn't too bad where it's at... besides with the help of mods I'm probably going to be reworking on a lot of parts so it'll probably increase SR by itself... (?)
