yes, communication in third party bots is still a problem, although pierre also did some voice stuff in his RACC. I'm trying to use some kind of translation from the normal squad commands to radio messages, so that the user "sees" more of the communication going on.
It's like with HL1 ... the unability to throw grenades - a marine throwing a grenade near to himself just yelled "holy shit", nobody complained, everybody said it was cool
so communication is quite an important step, even the chat functionality of some bots appears somewhat useful to the average user.
