Major suspected bug on turrets in twisted treeline
Unfortunately, I cannot provide a screenshot, but currently, after patch 4.20, a level 3 bruiser can solo take down a turret in Twisted Treeline at the mark of 3 minutes in around 15 seconds. Armor on turrets seems to become negative when minions are near on that map. This was not the case in 4.19. Bruisers at level 6 can 4-5 shots a turret.
Thanks for consideration,
