A possible solution to turrets.
So my thoughts are what all 4 waves of towers did something different?
Like maybe the first turret could be weaker than it is now and fire a little faster? And the next one apply like a 3 round burst all dealing 40% of its AD and the next one laser and the nexus turrets idk about those yet.
Anyway you might not like what's stated above, but the point is for all towers do different things.
