MfD is more of a personal preference. It's good for the gates, but it feels to gimp the DPS during burn by a significant margin. If MfD feels better, go ahead and use it but it's definately not necessary. I did use MfD for the early progress on Horridon but had anticipation for our first kill and every kill since then.

Depends a lot on the situation though and that being said, at most I do use FoK just a few times at most.
The macro you provided I would consider as mandatory, it really simplifies the burn phase and thus gives more time to focus on dealing damage. What I'm used to do with the macro is to hit it twice after spending a couple of global cooldowns (all depending on how close to add might be, of course), hitting the macro twice and spending a few globals again. After doing this for the time that Jalak is present, direhorn spirit should be quite far and you don't need to push the spirit away that often.
I do have a slightly different macro though, to avoid having separate macros for horridon and tortos. Works wonders.
I wish the best of luck for OP and everyone else progressing. :-)
