My issue with blink champs.
I think Blinking is a particularly frustrating mechanic, since it usually had damage tied to it and it enables the enemy champ to juke really heavy. Riot really needs to add a cost or some counterplay to blinks like Zed, Kat, and Leblanc. I'd suggest either higher cd on Kat's shunpo and no reset for it or that it costs %health or that it gives flat resistance compared to %damage reduction(why does an assassin have tanky initiation?), Zed and leblanc need lower windows or higher costs on their blinks since they are basic abilities and provide most of their kit damage and mobility. Ez, Lissandra, and Shaco aren't as frustrating because there's visual's showing that they are blinking and there's usually an animation on it instead of instant pop and there. Kass and Akalie doesn't even get their blink till 6 and it's costs are high or low range to combo it.
