There has been some dicussion about a human medic, but it could be that it would unbalance the game.
Why not make a support class?
------------------------------
Humans:
Medic: Costs 900 credits, available at Stage 2.
Has the ability to heal humans (rly?), works the same as the medkit, but only heals 50, and can also do only 1 healthpack at the time, till the previous healthpack has healed the person, carries 5 or 10 shots (depends on the balance).
In addition to that, when the medic reaches stage 3, the medic has a short range toxic weapon that deals damage around the same as alien poisen would do (does not work on dretches), the higher the HP of the alien, the more damage it will do, for example it would do 100 damage to a full health tyrant of time, but only 50 damage if the tyrant only has 200 HP, to prevent poisen spamming, it wont work multiple times at a time, like the alien poisen.
Medics wont be able to carry anything else besides these thing, except extra armour (excluding Battlesuit).
------------------------------
Aliens:
Costs 4 evos, available at Stage 2, has 125 HP, advanced has 150 HP
This alien class also has the ability to heal, this only works when an alien is closeby and issnt taking any damage, the healing would be a quarter the booster does at stage 2 (in example, if an alien heals 4 HP a second, it would heal 5 HP if the support class alien is around, not 8 like a booster would do), in addition to that, this doesnt work for the tyrant, in stage 3, the healing amount is doubled, to the half the booster would do.
In addition to this this class is also able to give out poisen to other aliens, in addition, he always has poisen on itsself, the poisen would last around half the time the poisen would do from the booster on the alien team , in addition, this class also has the ability to do a short range spit, if it hits a human, it gets 15 damage for unarmourd human, 5 damage for armourd, and 1 for Battlesuit and would also poisen for 3 seconds each less damage every second, if it lands on the floor, it would damage any human that would step on it (no poisen), the spit on the floor would dissapear in 5 seconds or if this class has more than 3 other spits on the floor.
Don't know any name for this class atm.

I guess this would wrap it up, comments to this idea would be appriciated
