Master Yi's Q untargetable duration have beed decreased since beginning season 5.
If you play yi alot, you ll notice, it a hidden nerf and not include in any patch, and it acceptable nerf when the new jungle monster was easier to regen. But the new patience system bring new face to the jungle, and i think it time to reverse the nerf. If it say untargetable, i should be safe until i done using my Q, but Yi keep dieing when he havent done any damage to enemy yet on his Q. WHY?
