There's hard, intuitive, easy and then there's healer rotations and then there's new summoner.

The DPS role exists solely to do damage, there is no justification in any of them having a rotation simpler than any and every healer - particularly when the reasoning behind lobotomising the healer role was to encourage the players to focus on the responsibilities of that role (healing for those hard of thinking). Whether or not the devs line of reasoning had any basis in the reality of their game design is neither here nor there.
