[AKACAT]

This confuses the hell out of me. I suspect it's something left over from people playing Red Mage, but even that makes minimal sense. Why do people spend ~40 MP (varying by use of Light Arts and Conserve MP procs) to slightly reduce the recast timer on Haste? Even pretending that I didn't have to cast it on 3-5 people (and, yes, I've maintained merit parties as the sole source of both Haste and healing with five melees), I'm rarely /healing to recover MP, certainly not long enough to justify shaving a few seconds off my Haste cycle by spending the same amount of MP I might recover while on my knees.

I used to start my haste rotation by casting on myself not to speed up my casting time but so I had an alert that the haste was about to wear on the first party member in the casting order. Then as soon as mine wore I'd recast haste on myself and start the casting cycle on the pt. It didn't take enough mp from me to worry about and it helped me keep the pt hasted constantly.
