Well speaking strictly from my point of view that the ultimate bot will be indistinguishable from a human player:
I saw no grenades
When shooting bots in the back, they don't seem to react (veteran human players are generally aware of all around them)
Bots set up at guard waypoints seem to be there for life (this would be an excellent option for a waypointer, if they also had an option to have the bot just hold that position until backup arrived)
I would like to see the bots stick together, does formsquad work?
In keeping with the image of a human player, they might take the weapon (if it is better than what they have) of the player they just killed

I haven't really played with it enough to be certain that the above mentioned points are valid. If I have simply overlooked something, please forgive me. I do intend to play with Shrikebot much more. I really do like playing with these guys.
