I love playing gang garrison 2, and one of my favorite classes to play as is the

. However, I feel the constructor lacks the true abilities that he has in TF2. Because all he has is a sentry gun, and adding teleporters and dispensers may be OP, I suggest that engineers should have passive repair.
Basically, when an engineer stands on a

of their own team, it heals, at about the same rate as the medic passive heals. A way to implement this could be a collision check from the sentry gun for a team's engineer, and if an engineer was in contact, it would begin healing slowly, and continue until collision ended.
I hope the idea is given adequate thought, and hopefully is added. Thank you!
