here's a suggestion to buff towers
make them serve as cover.
essentially, towers would be a circle of wind walls. any projectiles passing through them would be blocked, dealing damage to the tower only if it's something that currently does.
this provides a strategic advantage to fighting under your tower. with good play you could negate damage being directed at you.
this would also make multi-man ganks on bot towers less effective, as ADCs can't DPS defenders as easily.
