Some unit ideas from me

Whats about a medic unit for each team? as long as you are in touch! you get health

( You have to touch the person/skin) But only one per team...
Or flying mines? 1 per team, and only build able from the build class?
And whats about a "troop" system? To increase team play? For example:
Humans: If a person is in Battlesuit and two are in maximal light suit they get attack boost?
Aliens: One tyrant and maximal two marus get attack boost?
Or aliens could spray an acid swallow? When marines run over it they lose speed?
And marines could spray an anti biomorph acid that make damage to aliens?
And whats up with rade/wrath? After killing two marines(aliens) with less than 10 HP a marine/alien get in rage/ wrath with a hp bonus of 50?
well some ideas to make the game more fun ^^ Surely you could change the effects of these ideas
