AI seems a bit easy ?

Hello guys I played few games (10 or so) and i can already beat highest difficulty in late game pretty much every time. Is it just me or do you guys agree ? AI hero doesnt kill camps too much and often just running arround. It feels a bit dissapointing to not have proper challenge. I havent try online because one game could take several hours.

Edit: Im not trying to flex or anything. I wouldnt consider myself PRO by any means as i always read tooltips.
