i dont think mobility have anything to do with dps numbers. Blm is highest caster dps because they have no party dps utility, samurai is highest melee dps because they dont have anything else than slashing debuff that warrior/ninja already have. summoner is nearly same than red mage because summoner and red mage offer both raid dps utility. Mobility really never been problem once you know the fight and know where you should stand in the fight. Same can be said you have to know do you wanna push aetherflows earlier or later depends how much downtime the bosses have. It is part of boss progression.
