For my part, I 100% found the mana issue annoying and am glad they reduced our MP costs. Even putting aside the fact that RDM would run out of mana with or without lucid, the simple fact that they had to use lucid just to perform their standard DPS rotation for a while was an outrageous restriction on a job that already gets the short end of the stick every step of the way. Short of actually giving us useful spells or buffing out potencies, this at least was the very least they could do to help Red Mage compete a little bit less poorly compared to other DPS jobs.
