Turrets taking extra damage?

Turrets don't really seem weak with their effective hp, practically the same and will be exactly once raised to 4000.

What really makes them seem weaker is they're taking damage from more sources then they used to.

Alot of random on hit effects seem to now effect them. Red buff, wits end and nashors. RFC got added and I think shiv may work too now. Teemo's E does not still. Dunno about Bork, but AP on-hit Yi on towers is hilarious with devourer.

Certain consumable effects may or may not work, these don't seem to have been effected but I may be wrong. Nasus and Wu Q, along with spellblade always has worked, Caits headshot still does not, and probably Dravens axes don't as well. Maybe this thread could produce a list of things that didn't before but now do.

Was this really intended? I don't believe it makes turrets too weak, but it lowers the proportional gap between pushing ability of adcs and other champions imo. If adc (ranged and melee) pushed at a 10 and others at a 5, but now adcs push at 15 and others 10, adcs only push 50% harder, where they used to push 100% harder. Numbers just examples.

I see it as concerning, though I haven't taken any issue with it, adcs are still plentiful in games..to a disturbing degree sometimes.
