A slight Jinx nerf

Jinx is an ADC who has a very powerful and versatile kit. With her Q, she has the choice of having either an attack speed steriod stronger than Tristana's with the only limitation being a few autos needed to ramp it up, or extreme attack range which allows her to AOE crit your team. She has great CC, and her ultimate is an execute which is excellent for ADCs who want to get fed anyway.

Her main weakness, lack of mobility, is somewhat counteracted by her enormous range when her q is active and her CC, making it extremely easy for her to position herself in a safe location.

She's good in the early game in laning phase, where her rockets range makes it fairly easy for her to poke down her enemies, or cs from a range if behind. She's great in the mid-game with her strong attack speed steriod, making it incredibly easy to push down tower after tower and take objectives, and she's great in the late game with her AOE crits and excellent pick potential.

Overall she's an extremely good ADC who is very versatile. My personal problem with her is that she's a bit TOO good at everything, she's kinda like the lee sin of the ADCs.

I'd just like to change one little thing about her, to make laning against her a bit more manageable and add some counterplay and interesting decision making to her kit.

Switcheroo: Cooldown increased from 0.9 seconds to 6/5/4/3/2.

With this one little change it means Jinx can no longer seamlessly jump between her long range rockets and her minigun as much as she wants, making poking in lane with it a bit more difficult. It gives some windows of opportunity for her enemies to jump in and deal damage to her from afar while she is in minigun form, or pounce into close range while she's in rocket form and won't be able to deal as much damage to you in close range as she usually would. At the moment Jinx essentially has both of her Q stances at the same time, as its cooldown is fast enough that she can pretty much choose with which gun she wants to attack at any moment in the game and not have any additional decision making involved, no prediction, no way for the enemy to use her stances to their advantage.
