Some observations about Elise and Katank.

Lets first talk about Katarina since i linked the match history. The thing i want to analyze is the fact that even if she built full tank, she managed to deal lots of damage (compare damage with Twisted Fate) and maintain a costant threat across the game. I know that I actually gave her some kills in laning phase and got easily harrassed by her pokes and ganks as gp. But the fact that she didn't build even a single ap item and snowball the entire match means that there is something wrong with her. Considering that her damage was considerable despite her build, means that her base damage is too high, similar to the old akali tank top meta which was viable due to her reliable base damage. I think that some nerfs to her base damage must be taken in consideration due to this (i hope) not intended build reliabilty.

Now i want to talk about Elise and how she is reacting to the new jungle. I may say that the following is more like a personal feedback more like than the fact observation of katank. Myself, as a main Elise, i found that the new jungle is making elise struggle in her early game. Many people will surely reply to this with "That's intended, they wanted to drop the gank potential and jungle clear of junglers with recent nerfs", that's right, but it's also true that some junglers have some "unique" aspects that can make the decision of picking someone over someone else. Eilse's case is that one of her main aspects is that she had a fast jungle clear, however, she has been recently hit by the jungle changes. Her camp clear at gromp, red, blue and wolves didn't change much, however she got particularly affected by the raptors and the krugs. You can notice that her winrate dropped a lot in these recent patches. In 6.22 she was in a fairly good spot with 49% win rate, but now she dropped to 46%. After lot of games i noticed that she struggles a lot now for early ganks. With recent changes to exp, it's now harder to gank in early game since you need the exp from raptors to have an appropriate level to gank a lane, both solo and bot. I think that some buffs to her human W (just a simple base damage and scaling increase to help clear a little bit those aoe camps), a slight buff on cds (R and W (human) ) and a slight increase to her attack speed base stat can be enough to give her a little help for early game.
