Is there any Tech champ that can’t be reliably CGR’ed or Red Mags’ed?

Apart from Nimrod which I already know about.

Okay, I might get disagrees with this but my bet would be Rocket Raccoon.

He has power drain, armor break, and heal block, but the clincher is that he's non-metal to counter Mags and he's a hero so no debuff against CGR. Add on the fact that CGR is Metal which makes Rocket gain more scrap from him than normal.

Yes, he may be fragile as a defender but as an attacker he'll be good against Mags and CGR

I always use him against mags if I don't draft nimrod. Sub-40 second kills with very high health left
