I think I made a thread asking about Foe's before, but I never know how people are going to react to a necropost. Anyway...
1. Besides casters and healers, do DRK, NIN, or any other jobs with some "magic" looking skills benefit from this at all?
2. I'm not sure what do as far as dungeons when I'm with caster jobs. I used to just save BV + Foe's for bosses, but I've recently been trying to see if I can keep Foe's going for trash as well. The problem I run into is my MP doesn't regenerate quite fast enough to have it up for every trash pack, or worse I'm left with a small sliver when we get to a boss. So how do I need to use Foe's in dungeons? Should I be popping ethers to keep as much uptime on it as possible?
Also, I DO try to use Foe's for healers as well but not every healer seems very excited about helping with damage.
