New champion passive ideas

I would like to suggest new passives. It's been floating in my head for a while.

Ok, here I go:

1. Upon slowing/stunning your enemies, the next spell will become free. There is a cooldown for the passive.

2. Upon killing a unit, the champion temporarily gains a few ability power for a few seconds.

3. Your attacks marks vision on an enemy champion for a few seconds. There is a cooldown after the attack.

4. Upon killing an enemy ward, the ward turns into your ward and grants vision of the area for 60 seconds.

5. Your movement speed is converted into a percentage of ability power. (Yes, basically Hecarim's passive except ad is replaced with ap)

6. Upon hitting an enemy champion a couple of times, you become untargetable for a second. There is a cooldown after being untargetable.

7. Hitting enemies with on-hit effects grants movement speed.

8. Your attacks/spells temporarily reduce the vision radius of the enemy champion for a few seconds. There is a cooldown upon the attack.

9. Upon being hit from cc, grants bonus stats for a few seconds. There is a cooldown upon being hit from cc.

These are just simple passive ideas that I was thinking about. Please do give your feedback on these passives.
