5/65 Rank Up for Act 6

Palanthrax

I have 3 candidates for my next 5/65: Archangel sig 20, Cap IW sig 20, Iceman sig 120. I’ve already successfully used my boosted Iceman to clear Crossbones in 6.1.

I expect it will be between the first two, who will save me the most units for act 6 exploration?

I’d go with aa, used him a lot and cap needs a much higher sig to be extremely useful
