Hmm, I'm starting to think of nerfing him indirectly, maybe with a new enemy unit to spawn alongside him, so he is not that prevalent? hmmm
I felt like that a lot too, but i see that this enemy is the equivalent of a mage, so i don't know if he really needs to be nerfed, maybe just spawn less? I learned that by focusing on spreading allies with lvl 1 or lvl 2 is way better early on than focusing on getting lvl 3, and this helped with this enemy. The frustrating part is when they spawn together at a focused lane and destroy your no hit run lol but maybe it is still the players fault, lots to learn while playing.
