How about add drones? Another gamemod "Pirates, VIkings and Knights II" The pirates captain have a parrot works like a melee-attacking drone. I think drones are useful at many situations.
I want a SNAKE! That would be awesome. Im sitting here scunting yer base and then I send a snake into the barax to make you all scream and run out and fist you all!
Hrm. Scout drones that you deploy by holding down the fire key and then releasing; based on how long you held it down, the drone flies out that far ahead and floats. Acts as a radar / camera and has a weak, short-range anti-infantry gun (weaker than a level 1 turret, with a smaller area - not intended to kill infantry, but to harass them and force them out of cover.) Stays immobile at the location it's deployed to until it is destroyed or the scout releases another one (which has a cooldown.) Can be destroyed very easily even by small arms fire. It could be useful... distracting opponents, scanning for enemies, and so forth. Also, perhaps it could be fired at infantry or tanks to follow them. Infantry could kill it easily, but a tank (with no MG) would likely have trouble hitting it. It wouldn't hurt the tank, but would harass the driver if they get out to repair -- very useful against one of the most overpowered strategies at the moment.
Huh. That could be interesting, and would fit with the scout sticky grenades. It wouldn't do anything to people who just got out to repair their tanks, though. Mostly, the best use I can see for drones is to be able to do something to a tank that harasses drivers who try to solo everything, rapidly getting out and repairing between rushes... while if you have infantry covering you, they can easily shoot down the drone from outside its limited range and then repair.
