He just extends the game to the most boring 35+ minutes of your life by threatening a side lane and E’ing away. No solo laner can match him because he’s very interactive with R.
Playing ring around the rosie for 35 minutes and hoping your team knows how to outplay him fucking sucks.
Horrible champion
At very least Riot should make his ult not castable while stunned, so that playing him would take ANY skill whatsoever
But hey, better spend valuable balance resources to make Azir soldiers proc Nashors
