Who utilizes Warmog's Heart the best?
So i played
the other day, was vs an all AD comp and so after stacking some armor i got some health to support it, and warmogs was my item of choice. I really liked being able to join team fights then run away when i got low and just regen all my HP back up when i got to the side lane to split push. Seeing as not many people chase singed ;D it wasn't a hard task.
So my question is, who utilizes the insane regen the best? I know people like mundo and voli get it, but i dont feel like they really utilize the Warmog's Heart part as well as Singed does, at least in my example/situation.
Thoughts?
Edit: I bet j4 could be pretty solid with it? Swag flag in and out? :)
She was partly why it now requires at least 3k health.
Health is bad on raka, but warmogs regen is insane
Nobody expects the banana.
generate another 3% of his hp WHILE in combat.
. If you can position well late game, you can go through an entire teamfight without taking damage, thus healing others every 2 seconds without losing any net health.
does fantastic with multiple 

Stay out of the fight for 8 seconds and you're healing faster than the respawn pad
