Why can't we just have combo chains?

[Arohk]

I too would like this as an option. Not really the best for healers but when I'm using controller hotbar space for a 1-2-3, I would like this.

what combo chains do healers have? my white mage does not have any combo chains,

As long as the ability is useless on it's own, there is no reason to waste an additional hotkey for something else, i'd really like to bind my defensive abilities but there is simply no space.
