In D3 it wouldn’t. but now that D4 has multiplayer only, not only do you have to deal with the chat spam, you can easily have a much higher bot to player ratio.
The servers will have to commit more resources to host the bots.
Login queues will go up.
They can come in and swarm the PvP area constantly.
You’ll see party trains of the bots practically overlapping as they run around the open world farming gold.
Saw those bots in lost ark all the time. I don’t want that ever again.
