Towers honestly need to get buffed.
No beating around the bush, this whole thing with towers not doing any damage or outright ignoring people damaging you under turret is simply stupid.
Even at lv 1, someone squishy like Teemo can just walk up to you, kill you under tower and then run away with half their health intact. I'd honestly expect the tower damage to multiply the more shots someone takes, but it feels as if it decreases.
, hell, even a lv 2
