erthtk and tk have a completely different playstyle to the striking mods, theyre not focused on comebacks and chaaing at all, im not the best person to explain this, but although the aim is pretty much tge same with the focus usally being damage not disqualification, the meta is totally different

the problem with having 3 is that this means the peobability of having one of these mods is increased compared with kicking and grappling, unless you can find another mod that is suitable for each of these

rb_greykido or spiritwrestling with abd and greykido perhaps for grappling, but what about for kicking?
