Remove Warmog's
Warmog's is a seriously cancerous item, with spirit visage certain champs gain ridiculous amounts of hp regen. Udyr is the most problematic at the moment, but Garen and Mundo also become unbearable because of it. You literally step aside for a few moment then you are full hp again. Fight get low, run away heal then fight again, rinse and repeat.
The item need to be removed, it would create more balance concerning a lot of tanks. Being able to have that kind of hp regen along with the buff from spirit visage is dumb.
