How to Improve Turrets!
Honestly, RIOT has a great solution to turret problem, and they had it for the longest time.
Twisted Treeline.
Yes, Twisted Treeline's Turrets are INSANE and well made. Whatever these turrets do, they feel like Turrets. They melt tanks even at full build and they create necessary risk that a Turret should have. If they transfer the formula of TT's Turrets into SR games, we'll be finally forced to THINK before turret diving at level 4.
IF you haven't tried Twisted Treeline, it feels what Balance should be in this game.
