So now that Riot is trying to get more AP Junglers up in here...
What exactly is the Red buff going to be good for besides a health regen when smited? I'm just saying Having a red buff on an AP jungler is a little useless (especially when all you do is cast spells ie: Karthus, Annie, Anivia ,Brand, etc) unless you play Elise, Ekko, or any other AP champ that can basic attack rather well along as use their abilities. Every time I've gone JG Karthus or end up killing someone with red buff, I get my red buff and go "ok, now what the hell am I supposed to do with this red buff lol."
almost every champ has some sort of use of the Blue Buff because not only does it add some AP for the AP guys, but it also add some mana regen as well as %10 CDR for AP and AD champs whereas Red buff's debuff (slows + deals a small amount of True Damage) only applies to Basic attacks, and the only thing an AP jungler could benefit off of it is some HP regen.
So my proposition to buff Red is as Follows:
Crest of Cinders
"This unit's physical attacks and spells apply a debuff that slows the target's movement speed by 8 / 16 / 24% (5 / 10 / 15% for ranged attacks and AoE) for 3 seconds and a DoT that deals 5-56 bonus true damage twice (half for AoE). Also heals buff holder by 1% of their maximum health per 5 seconds. If the buff holder is slain, this buff is transferred to the killer."
It allows for AP champs to get the same benefit as the AD champs do, while giving any AoE damage at least a little bit of usefulness. As always, feedback (especially from a red :P lol) is appreciated!
