Sejuani's going to be heinously broken if she hits live in this state
just a heads up for anyone who wants their freelo next patch
all of sejuani's damage is loaded onto a passive with freakishly high % damage and no scaling, so if you want to destroy anyone with minimal effort, go full tank with a void staff.
on top of having probably the best single-target lockdown in the game now (up to 4 seconds of stun) her E->R combo lets her proc -- and reapply-- her passive, for a 50% max HP burst plus the base damages from E, R, and anything you use to pop the second frostbite, sejuani doesn't even need to stack up on you herself for her to be able to do this. put her next to a Renekton and enjoy him stacking her stun to full instantly and bursting you for the rest of your HP with no counterplay on your part. that's right, without any effort on your part whatsoever, you get one of the strongest executions in the game with 2 buttons on a nearly fulltank build. and all this, on top of being able to toss out up to a 5 second slow in a large AoE
but i'm sure this is just part of her 'skill expression.'
