Though this may seem weak, taking an ult to the face can be rewarding with this build. Sejuanni's abilities scale majorly off the HP you will be getting from Warmogs and the hp regen will make sure you can stand in for your team and take the hits, without losing much hp. Northern winds mixed with the Sunfire cape will really deteriorate the other team and with your ult, your carries can shred the little they have left. Tell me what you think :D
