[GAMEPLAY] Sejuani's W tooltip/gameplay.

So there are currently 1 of 2 things wrong with Sejuani's Flail of the Northern Winds, or maybe both things are wrong. Today (after the recent 4.21 rework to Sejuani's kit) I decided to test out her new W in a custom match. I rushed to level 9 and maxed her W, so it should deal 12% of a targets maximum HP on the initial hit.

What I discovered was that Sejuani's W initial damage is capped at 300, although nowhere in the tooltip does it list that it's capped. I also discovered that when attacking Dragon and Baron (The only 2 camps with MR) that the damage is first capped to 300, and then reduced by the % MR reduction that those 2 camps have.

This means that Sejuani's W only does 260 damage to a 5660 HP Dragon, although it is supposed to deal 523 damage including 23% MR reduction, or capped 300 damage. She also only deals 176 damage to a 11961 HP Baron (no baron debuff, it was the initial auto that I hit him with), although it was supposed to deal about 850 damage taking into account his 41% MR reduction, or capped 300 damage.

This is a serious problem with Sejuani's objective control since all of her big damage was moved into her W. Her W currently does less damage than her old Q (Although her Q's % bonus health damage was also capped to 300 on monster). You need to update her tooltip, and then also fix the bug with Sejuani's % hp damage being capped before the MR reduction and not after. This might also be a problem with other % HP damage junglers but I have not looked into them.
