If Zoe gets CC'd during her portal jump she should not port back until the CC wears off
The thing that makes something like a LeBlanc W balanced for instance IS the fact that if you catch her out when she uses distortion recklessly she is toast. There are a number of champions that can punish her severely in a lane for it now that distortion has a delay on it's return. LeBlanc's distortion also starts at an 18 second cooldown and since everyone maxes shatter orb now it stays that way until she is well past level 6.
I understand that Zoe is not supposed to as mechanical as LeBlanc but there has to be SOME risk to using portal jump recklessly in a lane and not just when a Zoe player decides to portal jump into a 1v5. Watching a Zoe player portal jump right beside me only to get hard CC'd but port back instantly is one of the biggest hand holding mechanics in the game next to Yasuo not being put in turret range when he ults.
