But how close are you to this top healer-DPS when you have to dedicate several GCD healing ?

So, in a sense, your DPS is a group effort...while tank's GCD usage is solely focused on itself.

On a sidenote, if you can win an end-game content without relying at all (or close) to your healing spells (Since oGCD are abilities), it means the content has a design issue.
