Buffing Zoe (Without Making Her Anti-Fun)
So I've been having a lot of fun with Zoe, but at the same time it can feel frustrating to play as her against other champions who feel like they do her job better, i.e. Leblanc, Zed, and so on. I do think she needs some buffs but at the same time I don't want her to go back to doing 80% of your health off 1 E at level 2, even if that can be blocked by hiding behind minions.
My idea to buff her is, instead of increasing her damage or utility with something like a lower E cooldown, to improve her mobility. Consider the fact that champions like Zed and Leblanc have far better mobility than her while also having higher base health and defense, not to mention better AoE damage in the case of Zed I think this is fair.
In exchange for how extremely squishy Zoe is, I think buffing her mobility is totally justified, allowing her to better chase or dodge attacks and ganks. That buff being allowing her to cancel blinking back to her original location, allowing her ultimate to essentially be a slower Flash with a short cooldown. The cooldown will be made a bit longer to balance this.
Portal Jump
COOLDOWN: 12 / 10 / 8
ACTIVE: After a brief delay, Zoe dives into a portal that she opens beneath her, blinking to the target location.
Zoe remains able to attack and cast abilities during Portal Jump, and can see over walls, but is unable to move. After 1 second, she blinks back to her cast location.
Zoe can recast Portal Jump 0.2 seconds after blinking and before blinking back to her original location to jump out of the portal and cancel the blink back to her original location.
