Is there really a need to use Flash constantly?

even not speed runs, any job that uses Dot's should be applying their DOTs to the adds. In the case of drg, blm, or mnk in a low lvl dungeon it's usually better to put your DoT's on the second monster because the first monster will die too fast. A smn's main damage comes from DoT and they have a move that copys the DoT's on one target to the surrounding mobs. A healer will DoT mob again usually not the main target because it will die too fast. All of these things are going to be generating enmity as you keep going, and if you don't keep track of hate on all the mobs I would just build hate on the main target and then use each part of my combo on a different add, so if I have 3 adds, they each get a different attack, based on how much enmity they need.
