Not sure about this one. Cause I feel that that's having down enemies gives you the chance to create a kill zone for anyone who tries to revive their allies
I would like them to swap back the medic and engineer's weapons. Engineer should be the heavy equipment specialist and give him better suppressing fire as other classes don't seem to have an issue taking a few shot in exchange for a head shot and the TTK is rather fast. With this the medic would be free to play a more supportive role.
(Would like to try) medics being the only ones that can revive allies and other classes being able to drag allies to safety. It would give emphasis to medics role and the medic bag could also extend the bleed time for down players. If these was the case reviving would be less of an issue but these might be more geared towards hard core mode. (Which I'm a fan)
