Riot, you need to fix spellvamp(Repost from GD).

It has been a horrible stat for entirely too long. Keeping a stat inherently non-viable for most of the game's cast because one or two champions are broken with it, namely Vladimir and Vladimir, is not a good thing. Yes, Vladimir abuses spellvamp when it's a decent stat. With how it's set up, of course he does, because there's nothing stopping him from doing so. Spellvamp is inherently more powerful on low cooldown low resource single target abilties like Transfusion. It's because single target abilities benefit from the full amount of spellvamp and AOE abilities take a large reduction.

If you used the same approach to AP, where every single target had a 1.0 AP ratio and every AOE ability had a .33 AP ratio, the entire game would be imbalanced. If you didn't have a low cooldown single target ability, you'd be worthless, and if you did you'd be amazing. And I don't even want to know how percent based damage scaling would work. Fear the mummy.

But, anyway, the game doesn't suffer from this problem because Riot created AP ratios. If an ability scaled too well, they could nerf it. Vladimir's transfusion currently has a mere .6. If an ability didn't scale well enough, they could buff it. Like Veigar's primordial burst scaling with 120% of your AP. Due to the mere existence of AP ratios, AP champions can balanced.

If there were spellvamp ratios, champions who rely on abilities to deal damage(Read: most of the cast) would be able to buy spellvamp and have it do something. If spellvamp was too overpowered on Vladimir, you could nerf spellvamp's effectiveness of Vladimir. Instead of nerfing the spellvamp items or nerfing parts of Vladimir that don't tie into his spellvamp, you could nerf Vladimir's spellvamp ratios. If you can't add an AD spellvamp item because it's too inherently powerful on a bruiser, like Udyr, you could nerf said bruiser's spellvamp ratios and allow champions like Talon and Pantheon to buy relevant sustain.

I wish spellvamp wasn't only a good stat on a handful of champions. So, Riot, I request that you add spellvamp ratios to damaging abilities. Or if such a request isn't a possibility, I'd like to hear why it is so.

Here's hoping this'll get a red reply where the other did not.
