[2022] Major changes coming to systematic healing items and runes live on PBE

Here to clarify the goals on these changes.

As a general principle, sustain (like any other stat), should come at a cost. If you want to deal a ton of damage, you usually sacrifice durability. If you wanna itemize to be a drain tank, you shouldn't also present a high damage threat.

So imagine this as a systemic pass at re-evaluating the cost of sustain. The early hints of these are seen in the Fighter Mythic changes over S11, with Goredrinker/DS having damage siphoned to cost their sustain power (also why they're not in this list).

AP champions as a generalization do not need sustain as a core stat as much as other classes. They are more burst reliant, have less combat contact time, and are meant to be weaker in sustained combat.

Obviously there are champs that break these normal standards and we will investigate them as needed (Ryze, Cass, Karthus). And before this goes to "just revert to old Rav Hunter", the rune was eventually tuned to only be viable on that subset of champs and near useless on every other mage.

Also for junglers, the omnivamp on the item is unchanged. I don't really understand how you're saying the 0% omnivamp at lvl 1 is the sole reason you are unable to jungle fizz.
