It's sometimes hard to tell if the engineer staring at your dead body is waiting for energy to revive you or trying to place a structure. I think it would be a good idea, both practically and artistically to add a white armband with a red cross or other symbol that represents a medic for the engineers with revive or healing upgrade. Comment, please
I made a thread about this previously http://forums.empiresmod.com/showthread.php?t=3693 but your suggestion seems like an easy fix (at least for the engy)...so i'll back it
I think this should give you say a blue cross if your a engineer, and a red cross if you have the Revive skill, so when your fighting a tought fight, and the engineers are running around reviving, they can revive the others who can revive first.
