pretty sure Lulu's W is bugged out I was just in a ranked match where I would cast it on someone and they would still use there ability's or attack. I casted it on Master Yi 5 different times before he would Q and the ability would go off then he would Q and nothing would happen same with Zed would W him and then he would ult. i could understand a "simultaneous" cast but they weren't like I casted W on Cait and then she Auto attacked me while being a snowman
If it was Yi and Zed, did you notice if they were using a Quicksilver Sash?
Edit: Ok, no that wasn't the case. I looked at your latest match (had Yi Zed and Cait so I can only assume that is the match) and none had a QSS or Mercurial Scimitar, plus you just said Cait attacked while clearly Polymorphed (aww, you use WW Lulu too?!).
Needs further testing.
Polymorph is a very fast projectile, not instant (boy I wish it was) so it is very possible to get an auto attack off right before you get polymorphed and it will probably look like you are attacking as a cute little squirrel
