Taric rework ideas

Just some random ideas I've been thinking about. Let me know what you think and what you would change

PASSIVE - After taric uses an ability, his armor lights up. If he hits an enemy champion or unit within 4 seconds, all ability cooldowns are reduced by 2 seconds(with the extra utility I'm suggesting for Taric, I don't think he needs the extra damage on his passive now. The CD reduction seems more than fine)

Q - Taric throws a green gem on an allied champion healing them for x amount over time. After the gem expires, allied unit gains 10% increased move speed Q - Taric throws a red gem on an enemy champion, reducing the healing received by x amount. After a certain amount of time, it explodes dealing damage. (Miss Fortunes rework got me thinking on this one. It makes sense for an ADC to not have grievous wounds but why not on a support? It would make Taric good against certain team comps. Vlad for example with gragas and a Nami on the team.

W - Passive - Gems grow on Tarics armor, reducing physical damage by x amount for himself and allies around him(as a visual update idea, instead of a circle of gems around taric, make them grow on Tarics armor) W - Active - Tarics gems burst off his armor, reducing enemy armor around him by x amount

I thought his W was fine as is so didn't really change anything other than how I think it should look on him

E - After a short delay, a gem shoots up from the ground in a small radius, stunning any enemy champions caught for x amount of seconds(point and click CC are not fun and don't really have a whole lot of counterplay. This removes that while also making it multi target if the enemy is grouped up.)

R - Tarics armor shatters and he goes into a rage causing gems to erupt from the ground in a radius around him slowing all champs caught in the area. Enemies caught take 10/15/20% more damage(I like this because it makes positioning for Taric key when he uses his ult. You cant just use it like he can now and get an instant boost to AD. Also makes adding things to his other abilities more acceptable since it will take more patients and timing when using it)

For his ult, I think the visual should look something like this video where he transforms, https://www.youtube.com/watch?v=jGy5ZJ8cSUE
