the poor warding isn't as big of a handicap with robots as it would be with humans
for humans, wards give you extra time to react to enemy movements and arrange ganks, check runes, etc. but the robots don't really need the reaction time bonus, and the information bonus may not be very valuable if they arent proactive about pushing and ganking.
