Nobody asks for complex rotations for tanks and healers. :) We ask either for not so boring gameplay when there is nothing to heal or for a gameplay that is vastly different compared to a dps job.
AFAIR with Endwalker there will be some changes for tanks. They will get more cooldowns which are useful for some situations etc.
