*ding*ding* we have a winner. That is how SE believes players are playing it, and thus that is how it's designed. If you want to adhere to some alternative meta, go right ahead, the lilies neither help nor hinder you.
Players somehow got this idea that the gauges on the jobs are some kind of limit break bar, that they are spending "points" on some bonus thing. You're not. If you are playing the game the way SE has designed it, you would be playing it this way, and the gauge would be unnecessary. They introduced the gauges just to spell it out what activates the proc's.
