Courage of the Colossus needs to be nerfed

Courage of the Colossus should be nerfed on its percent health because certain champs benefit WAY too much from it. I.E. Poppy: she already has a shield and all she has to do is build iceborn gauntlet and she becomes overwhelmingly difficult to deal with. I've played multiple games with a poppy on the other team and she is always extremely hard to kill and can even dive multiple people under towers and tank for WAY too long, while putting out so much consistent damage. Even if you manage to catch her out alone she can use her ability that stops dashes and just ult the team away or get away herself. There are plenty of other champs that benefit just as much but too many to iust. PLEASE DON'T BRING BACK THE TANK META.
