I've been playing a bunch of bot games lately as an easy lane farmer (I usually play support in pubs and I'm just practicing my carry role) and I've noticed that the bots nearly always mess up the lane equilibrium.

What my support will do is go far forward to harass and then the creeps will aggro and pull back, either into the tower range, or split the wave up so that there are multiple low HP creeps at a time.

I've noticed this with both Medium and Hard bots.

Apologies if this has been posted previously.
