Aegon buddy...
Stop at 180, you know you'll dupe it as soon as you waste the stones.
In addition to the ones named already:Tigra, Absorbing Man, Domino, Cassie Lang, Silk, Omega Sentinel, Ultron, Guardian, Nimrod, Crossbones, Attuma & Knull.
Groot at sig 200 is the best champ in the game. Long live Groot.

She needs max sig only if you truly care about her evade chance. In terms of power sting limits, the sweet spot is sig 87 IMO since her limit expanded to 37 power stings, and in grand scheme of value its not that important to waste 120 sigs for 3 stings, that won't even come into play in many short-medium length matchups

Quicksilver benefits highly from max sig. Not sure if he needs it, necessarily, though.
Aegon buddy... Maybe one day, don't have 6* Aegon
Doom if you like to slap.
