I made a very similar suggestion in a recent Vet thread, so needless to say I agree:
I do like my replacement idea for Fire Team a bit more, but yours is perfectly reasonable too.
Close and Kill I’m a little unsure about. I think it’s a pretty nice stat to give your team even at only 5%. 7.5% isn’t a crazy amount either mind you, I guess I’m just unconvinced that its pick rate isn’t more to do with right tree being generally undesirable and losing points to switching branches being pretty heavily punished in Vet tree. I see a world where we’re quite fine with it as is, because we’re already happy to be over there, our points don’t feel quite do thin, and move speed bonuses for the whole team are quite a scarce resource.
