Completely agree, and unless I'm mistaken all bots rely on Click To Move to function. Does any legitimate player actually use Click To Move? I didn't even know it existed till a couple of months ago. If Blizzard simply removed Click To Move, I'd go as far to say all bots would stop working and any that were made consequently would be no-where near as advanced.
Alas they don't, and I may be bold in saying it, but I believe it's because Blizzard still technically earns subscription money from bots.
