Every other medic gets support XP just by using their ability - throwing a health pack to the ground, deploying a healing station etc. If somebody uses the packs or station, further XP is awarded. However, Phoenix gets XP only when he actually heals someone. Using the ability doesn’t give him any XP in and of itself. That’s weird considering that basically any other character (not only medics) gets XP just by using their abilities, regardless of effect (just throwing a grenade gives combat XP, even if it doesn’t hit, etc.).
Thus, I propose for Phoenix to get some XP just for using the health pulse too. Make it +15 support XP or something, doesn’t have to be much. Just make it “equal” to other mercs.
