The only thing I have against Garret is his post Awakening competition. On stats alone he's an interesting off-tank but unlike Awakened Bernice he doesn't passively buff his tanking partner's defense. That makes him very expendable to vets who own or plan on shooting for a platinum or black heavy infantry.

But you know what? None of that really matters much in this case. Awakening isn't out yet, Golds don't take any more fodder than Silvers to CC and in the short term the OP just plain needs some tanks up and running. There's not much reason to avoid CCing Garret in this particular situation.
