It's a massive buff to Sunfire Cape, and would probably make it gamebreakingly overpowered on most tanks.

Imagine this. Sejuani builds Warmogs and this. 4000 health, means she deals 64~86 + 4~5% of of her  health per second. That is roughly 300 magic damage every second. For reference: Karthus needs 800 AP in order to outdamage that aura with Defile.

Keep the damage the way it currently is, make it more attractive to build it for its defenses, in my opinion.
