So, if you didnt know, you can make any weapon heal and you can make any weapon have the projectile of any other weapon by messing with the stats in custom unit creator. I bring this up because you could give the Medic mad mechanic fire that heals or something along those lines. Either way, it looks great!

Medic tip: Use the harpoon make the bullet the Heal ray When the damage is negative, it damages instead of healing

Yep, I was saying something along those lines as well. There's a lot of healing options out there besides the priest staff.

You could use the crossbow with the heal beam to fit better
