[Gamebreaking] Twisted Treeline Negative Turret Armor

Turrets in Twisted Treeline receive negative instead of reduced armor when minions remove the Reinforced Armor buff. Although the minions aren't quite in aggro range, they are both removing the R.A and sending the turret armor into the negative values, thus amplifying damage taken. A single wave of minions can take well over half of the turret on their own before 5 minutes (whereas before they'd do minor chip damage during the gank you attempted, etc). AD champions with a single item can 100---0% a turret in 5 to 7 auto attacks or so (had a non-fed Fiora with her Hydra whack the thing 6 times and it fell...). AP+AS champions (like Azir ^_^) can also participate in the shenanigans. Rito pls fix, etc etc.
