I think thats a good variation of mods.

Lenshu3ng, is competitive and balanced, pretty much a proven fact.

ABD boring af imho, but still balanced etc. the same with lenshu

Erthtkv2, the most balanced tk and as well viable for competition

I would maybe add wushu to the list. Thus we would have 1 mid tf stricking mod. 1 short tf stricking/kicking (ive never understood why those have to be separated) mod. 1 long tf stricking mod and 1 balanced grappling mod.

With those, there would be everything for everyone but the list would not be bloated.
