I think it's a great idea and brings another layer of gameplay to the battlefield a healer is 1 less attacker
I would like to see a robot called ghost which goes invisible for about 5 secs with maybe a quick dash ability so he can dodge out of danger like stalker but not stealth completely invisible

Just played on test server and mender and weyland they look and feel great I can't see why people would moan about these bots as they are great for tactical gameplay and not just a slugfest with orks ...
