Yo, In almost every game I meet a team of opposing bots in 2x2 and soloq arenas. What are you planning to do? Playing against artificial intelligence is not interesting at all.
And yes, I'm sure they are bots or similar software, as those who play can also confirm it, as well as the people themselves said they use the program.
I also did a lot of botting back in retail-wow and I can see immediately where the bot is and where the player is. There can be no mistake.
