Would you look at that, giving Sejuani a spammable %max health move makes her strong
Along with every other champ who can spam %health damage as everyone along with their mother gets it now.
Goodness I couldn't 1v1 a tank Sejuani as Darius late game because she could deal 12% of my max health every 4 seconds along with 400ish damage aoe over 4 seconds.
