Combat intuition also tells you relatively how far away you’re being aimed at from, based on the size of the wedge. This is useful for knowing when a guy is right behind you (huge wedge) or when a sniper has you in his sights (a very skinny yellow sliver)
I dont have any characters without combat intuition.
As for the original topic, I don’t use Grenade shooting, but only because I don’t use grenades all that much. Most times I prefer using pips to support my teammates, and the times i do use a grenade, its usually me just lobbing one into a room before I run in.
As a soldier, the one class where the ability would be useful to me, I end up using a GL attachment most of the time, making it useless.
