Ok here is the video of me doing mine. Its an old one so I'm going to add a bit of commentary and ways to improve what was done in the video.

1. Not shown in video: Before buffing, use all your items (Food, high breath mantle, reraise if u want). You can see the icons at the top
2. (not sure about other jobs but as mnk): Buff BEFORE engaging. Berserk will last the entire battle. Using JAs during the fight only adds to delay.
3. 39-40 secs: While fighting blue MR, I'd recommend facing back towards a pillar so when u do get empty seeded you don't go too far (unelss drawn in afterward).
4. 42 secs into the video. Aqua MR is at 1% and I just got empty seeded/drawn in. This is the perfect time to use a potion or 2 and get full before Contemplator pops.
5. 46 secs: Have done this plenty of times and it always works better with auto-target off, controls trying to change to MR is just funky w/o it.
6. For Contemplator pop, I highly recommend this macro. /item "Psychoanima" <stnpc> this will allow you to have MR targeted (your target) and still be able to use the anima on the Contemplator. If its been a bit since you've been empty seeded, I'd wait a sec or 2 before using the anima. Getting knocked back while trying to use the item will give you a nice chunk of delay before you can attempt to use it again.
7. Have a back up anima (Terro). If you don't finish the job before the Psychoanima wears off, this can put you in a sticky situation. Also have a macro for it.
Protips: Keep all meds macro'd; best for quick use.
That vid was my 2nd attempt, but using some of the tips I've pointed out I've been able to win with much higher HP using much less potions. On 2 occasions, I even beat it w/o using any potions nor chakra. I'll make an updated video next time I attempt this (should be today)
