Riot, you say you are open to revert changes when appropriate?

What's wrong with giving Kassadin back his Mres/lvl or Warrior's 5AD? Both are incredibly underperforming at all levels.

Kassadin, by his kit deemed to be way better in LCS than soloQ isn't even mentioned on the LCS anymore.

Warrior, once the dominant jungle item that surpressed the rest of the junglers, got a much deserved nerf, but this was followed by a buff/rework to all 3 other jungle items making them way better than Warrior. Currently, all warrior junglers have below 50% winrate other than Shaco thanks to his incredibly high playerbase avg games (in other words: shaco mains). Warrior being weaker than the rest makes sense, because it's mainly used by generalist champions. However, when these generalist champions have awful winrates and are even getting buffed individually (Vi, Lee Sin, wtf?) something is wrong.

Warrior will still be a blant and boring bunch of stats with no uniqueness, but I'm sure they'll be reintroducing it in the preseason 6. Until then, can we atleast make this item viable again by reverting a nerf that is no longer necessary?
