i had some ideas for a weapon set for medic so here it is

Primary-TF40
No arc
10% more fire rate
10% larger clip size
20%more ammo on pickup
20% less damage
10% longer reload speed

Ze Trimedi-12
Does not ubercharge
at 50%charge you can heal 2 targets at once at 100% charge you can heal 3 targets at once
getting shot decreases ubercharge
-25% ubercharge

Syringe
heals allies
enemies bleed
can be broken and not usable for 10 seconds
