can you pls recheck the range of archers? i was hitting an OL with my archer with autoattack and we had the same attack range. i have learned the archers will and it gives +100 range plus archer lvl 2 that gives you +50 range.. its cannot happen that we have same range and the OL can cast spells. something is wrong and i would to check it again..
Also i saw that often when i reach max range and hit 1 arrow to the mob and the mob is start buffing himself, my second autoattack is nearer it makes 2 steps closer and then hit an auto attack again.
