Katarina Counter Play
I'd like to open up a discussion about meaningful counter play.
I've been in a few games recently with Katarina and in these games I've found that her spells have no cast time, allowing her to simply dominate otherwise even duals. On the playing side this feels ok. I want to get to a champion: "boom" now I'm there -> instantly death spin them. Meanwhile on the receiving end there is not time to respond to this action in anyway. Not even one single basic attack.
As I play I tend to feel rage in this moment. I don't feel like I'm playing a person who has skillfully beaten me in a dual but instead that I'm dealing with an unbalanced unfair mechanic.

counterplay is pretty much any type of CC or escape. Just save your CC for her ult and she is basically shut down until she has it again because her damage is pretty Meh without her ult. Also if you have a dash or escape mechanic, also save that for her ult for the same reason as above. Her laning phase isn't that great compared to other Mid Champions, similar (yet a little better than)
, especially after the damage nerf to her ult at lower levels.
or Twisted Fate
where they feel like they have the means to respond to a treat but without the slightest window to see an attack is happening Kat can use her full combo of damage (q,w,e) without risking the time for a responding time of less than a second. This feels like it's over powered.
and 
Bear stance to run up and stun her then phoenix stance to burst her down. Uydr is a monster against Kat, he justs needs a mr item
