All these balance changes and i'm still seeing units bugging out and standing around doing nothing.

By far the most aggravating issue TFT has had (besides rng item drop amounts on the first waves) has been when units will just bug out and do nothing. Shyvana is one of the strongest units in the game, I got a tier 3 one with warmogs and hextech, and she died because after casting her ability she stood still, not moving or attacking, for TEN SECONDS while the enemy team wiped the rest of my team. I see this shit every game still and it makes balance changes not matter in the fucking slightest because it's essentially a whole nother layer of RNG on top of a game mode that's almost exclusively RNG, except instead of getting lucky and getting good units/items, its getting lucky and having your important unit actually do something in the fight instead of effectively being AFK. If I wanted to see units AFK every match i'd just play solo queue normals.
