This is the League of Tower Diving

Because the towers don't do crap anymore and once your laner leaves/dies, you are immediately dived under turret and can't do shit. I've learned as support/adc, to immediately go back once my laner goes back or dies, because then I get turned on and can't hold the lane until they come back. Also come mid game, once the enemy decides to team up, it's like a five player gang up party on mid lane and they rush the mid turret too and you can't do crap cause your team is still laning and once they get the turret you and you're jungler are immediately jumped on if you are stupid enough to try and protect it.

TL:DR Riot, this is supposed to be the League of Legends. Not the League of Tower Diving. Buff the turrets so they can hold longer and focus champions better if two or more dive.
