Some difficult stuff I will attempt to add once I'm done with finals

The wait helps balance it though. If you had something with a giant mag and super awesome fire rate that you could move quickly with would be super OP I think.

For my comments to what he said
I love the idea of a stronger shotgun. I love one shot kills, but it does need to be balanced.
I love the idea of suppression weapons; though I believe there should not be any indicator like defend. See what I said above for what else I think
I think turrets could be useful, but they would have to be implemented right. I think it might be best to have limited amount of time they can fire or bullets they have. Maybe a new kind of ammo you have to collect to use them, also I like victor's idea for implementing them.
I dislike the idea of essence transfer. I think each entity should be their own to run on their own. I think if there is a problem with bot ai you should fix it or report it. Fix the problem not try and fix one solution.
Marking enemies is an interesting concept. I think there could be a place for that, though I would place most of the rest of the list over this.
