I have 5 TE on everything on my team so far except Gadius and RRH (both fully rainbow). I'm using RRH because I have no other options and can't afford 2 Orchid's. I'm planning on putting 5 RCV on XM, or 3 RCV + 2 SDR. I heard from a friend who has XM (and a non-hyper team) that RCV isn't that great since there's no RCV multiplier and the HP pool is quite large. Another option for inherit is a damage enhancer. I've seen people use Freyr, Sun Quan, and Arcline (Arcline being the ideal damage enhance).
