ACccording to some reports, Yis ult also makes him immune to Singes Poison Trail.
Please do something about Yi's ult.
It lasts too long, refreshes, makes him immune to slow/exhaust, and basically is a game ender unless your team has 4-5 stuns.
I suggest making it lower duration (8 sec or so), do not allow it to auto-refresh, and make it only stop slows, not the blind effect of exhaust.
Right now it's almost impossble to counter a well-played yi without an entire team of stunners.
