Blizzard is endorsing pug players being forced to play entire WSG games as a ghost camped at the GY by 10-warlord premades.
So Yes, it must be OK to BOT because what is the difference between a BOT spending the entire game as a ghost at the graveyard, or a player in full control, but still spending every single game as a ghost in the graveyard anyway.
So they must be allowing bots - whats the point of being at the PC while queuing for this garbage they are peddling to us as being acceptable.
