Riot claimed to be buffing/working on the turrets
I really hope they make them hit harder and tankier. This doesn't only apply to Summoner's Rift, but also the other maps.
Howling Abyss: strong until maybe 8 mins, then they become squishier than a level 1 Teemo. I know it's to progress things, but still, you can dive and tank the turrets for so long by only building some tankiness. Even squishy champions that are full AD or AP have no difficulties taking tower shots without being remotely close to dying.
The Crystal Scar/Dominion: The turrets there... Are just weak. They're indestructable, but they don't hit for any damage more or less. They are only there to look scary, not to actually stop the dives. I would rather see them have the Summoner's Rift's cleaving lazer, that actually makes it difficult-ish diving for longer periods.
