I know this may be intended, but it seems a bit stupid. If fizz troll poles while Azir ults him, he simply bounces through unaffected. I think this may need to be changed. so that fizz doesn't completely murder Azir.
There's a rather large difference between a bug with Azir's ultimate and your belief that Fizz shouldn't be able to Playful-Trickster over it.
The untargetability works the same way Vladimir's Sanguine Pool or Zhonya's Hourglass's active works. They make you entirely immune to CC and abilities during the time the untargetability is active. This means there's no reason Azir's Emperor's Divide should go through, just like any other form of CC.
Only thing left is to accept that Fizz counters your ultimate. These posts should be in Gameplay and Balance, right?
