Dr_SpamomanFeels like this will remove some of the surprise element of kritz. Usually you have to go spy or get close enough to the medic to see if it is kritz or uber. Being able to tell what medigun is used and % from across the map makes kritz way less viable.
Doesnt renaming the medigun hide what weapon its being used? Spies could tell because the 3D model in the HUD would show the weapon model regardless. But Im pretty sure seeing the ubercharge data in the HUD that you could also see as a spy doesnt tell you the medigun being used, just the custom name.
