You don't need CLS speed to be 250 to solo rancor, especially if by solo you mean 1 team as opposed to 1 toon. It can be done easily with just CLS, QJG, and Rex all at around 200 speed no zetas. My CLS can solo it by himself, he's at 226 speed and only 1 zeta on "It Binds All Things." You will need some speed secondaries on mods, but nothing too crazy.
I've solo'd it completely with just Wiggs and CLS, so you definitely can with your CLS. It's a whole lot easier though with Rex, Jyn, or any other TM reduction characters. R2 is nice as well if he's going to get a move to stealth everyone you don't want to get hit.
