User blog comment:Braumissomanly/Whats with all the percentage damage?/@comment-3148314-20140817105555

1. as everyone said, it's given to bruisers to kill other tanks. I've always loved % damage, so I don't complain. :)

2. You could ask the same question about % heals - with the difference, that some people still don't realise their strength ("omg Sona heal so weak" etc).

2.1. They removed an almost OP-%-missing-health-AoE heal from Karma when they reworked her (something that was considered "weakest heal in lol" afair) and now, they suddenly give % missing health back to (two) supports...yes, I know that Karma has % missing health on W, but she can't heal allies anymore.
