Help Understanding Speed

Nihilus dispells on basic and has a comparable hp/prot pool. You could try him. Another option is to just be careful about when you hit that tactical genius and just make sure it's after Baze has his aoe on cooldown, or when you have him stunned by R2, that's generally the route I go with my CLS team. He'll still get the tm of course, but you'll have extra time to make use of the buffs, and his basic is a minimal threat.
