Engineers should make sentry nests
sentry gun Ai is a bit more clever
medics can build and deploy uber charges
Robo engineers will build dispensers and sentry guns
Make the robo engineer's current building into a teleporter that MVM bots go through
Adjustable AI levels (Think its already in the game but not sure)
Snipers stay where they are and typically dont move too much
Kill feed
and
More guns for the bots (Sandvich bonk etc)
