In tempus we have given the soldier a constant 400 HP buff. This means you don't have to worry about switching between gunboats/shotgun, you don't have to constantly be checking your health, and its consistent for everyone.
Currently we have left demo untouched, after we initially asked some jumpers. Over time though, the majority of the people who have played in the server and we have chatted have wondered why demo doesn't have HP regen to 175. To be clear, no overheal, that is not even being considered. A constant 175 HP regen would allow less worrying about health, especially on the large amount of maps that aren't covered in a trigger hurt.
Feedback please!
EDIT: Demo HP Regen has been implemented!
