Why Nerf Elise?

Disclaimer: I have never played Elise. In fact, I hate Elise. I play Mumu when I jungle.

That said, I have to question why Elise is the target of jungle nerfs this patch.

Right now Elise and Diana are really the only two viable mage junglers. Prove me wrong, but the only other mage jungler I saw all patch 5.15 was a Malzahar that accidentally forgot to switch with Shyvanna at champ select.

Elise and Diana both have different roles as junglers. This is a good thing.

Elise: gank lanes, get team fed. Team wrecks. Diana: gank lanes, get fed. Diana wrecks. Who needs teams?

They are both equally good at their jobs, respectively. According to na.op.gg, this past week accross all divisions Diana and Elise have a 51.77% win rate.

Despite their different play styles, Elise and Diana are really good at one thing:

**Countering all devourer junglers. **

Both Elise and Diana are exceptionally good at snowballing a team before the enemy jungler can become sated and dominate the game.

However, they are entirely dependant on those early game ganks to do so. Fail a few ganks? Your team will probably lose. This is the risk you take when you play Diana and Elise.

So why is Elise getting nerfed? Right now the highest winrate junglers are dominated by devourer junglers, with Mumu and Maphite being the only two competatively high win-rate cinderhulk users.

(Side note: late game mumu and Malphite also are hurt a bit by the new cinderhulk change. But if you let a devourer jungler get to late game you are probably going to lose anyways)

Xin: 54% winrate Warwick: 53.6% winrate Kayle, Udyr: 52% winrate.

These devourer junglers all have higher winrates than either Elise or Diana, and are really only countered by the early ganks that Elise and Diana bring, but Elise is the one getting nerfed despite having an identical winrate as Diana.

I feel like with the Elise nerf that jungle diversity is one step closer to becoming devourer diversity, so I have to ask:

Why nerf Elise when she is one of the best counters to the extemely high winrate devourer jungle meta and doesn't even have a great winrate?
