If they simply were equivalent for multi and single target it'd be fine. But C&S doesn't even have a heal effect, if it was something a 600 or 800 potency heal (more or less what you'd get from using AD on a pack of ennemies) then yeah I'd get it.
But here it's just... bad. Yeah it removes a bit of spammy aspect in openers, but then Edge is now 1 second of CD, so you can just spam that instead.
