Proposed Clairvoyance Buffs

I think that the Clairvoyance spell should be picked if you think vision will be more important than usual in this match. I believe it could fill a niche there. I have a few suggestions that could make it useful in that regard. I wouldn't want all of these changes but I think a couple of them could possibly make Clairvoyance useful in some situations.

1. Increases your green and pink ward caps by 1 if you have the spell.

2. Increases the vision or cast range of wards by 15% if you have the spell.

3. Lowers the cooldown of your trinket by 40% (or whatever value makes sense) if you have the spell.

4. Reveals enemy wards like Sweeping Lens.

5. Gives assists if it reveals the location of an enemy. (nothing to do with the vision game, just something that would be a reasonable buff to the spell)

6. Make Sightstone completion cost and trinket upgrade cost significantly lower if you have the spell.

I had a few more thoughts but I can't remember them right now so I might post some more later.
