Turrets feel much better on Treeline.
I've played at least 90 games in Treeline in the past few weeks (compared to maybe 20 on SR) and have just made a full transition to being a 3s player, and I gotta say, turrets feel SO much better on this map.
Tossing all arguments about different meta/playstyle/etc. aside, yes, the lane turrets do feel kinda weak and it seems like they get hit harder. But inhib/nexus turrets, holy shit, do they actually feel like they matter. I get scared doing turret dives even when I'm ahead because I know if we don't get a kill immediately, I'm probably going to die instead. Even when I'm a fed Ornn with huge W shields and FotM active to keep me beefy, I know I can't stay there too long.
Dunno about actual statistic differences for most turrets, but I know Nexus turret for sure hits INCREDIBLY hard and insanely fast compared to any and all SR towers right now.
