If i was Blizzard i would do comp stomp like this: I would put players just to normal AB but i would change in interface that opposing teams names are changed into bot names and all signs of them being real players would be diminished. So no one would ever know they are playing against real players but they would think other side is bots. And i would eat popcorn and read forums where players would complain about bots being tooeasy/toohard.
Well if i was Blizzard and BossBlizzard would say “No you cannot go with your plan, you gotta create those bots for real!” my AB ai bots would be more realistic. Every team would have 1-3 bots jumping uselessly around or afking in some corner. Then it would have 0-2 extremely well geared and skilled bots that would farm the whole team on gates just 2 of them. It would also have couple of bots leashed on roads in the way they never reach any flags but they would fight hard on their locations (one them would be programmed to shout constant insult on chat to bots that try take flags). Rest of the bots would run from objective to objective taking flags. I would also add bot that guards flag but it would never be implemented in actual game.
Considering that I have yet to get the Arathi Perfection due to my teammates being incapable of executing the simplest strategy, I think that bots are already difficult enough…
