I got this today on my 5 man group and went ahead and did it, missed the Make it Count timer by ~5 mins but I spent a good 10 mins on macros and stuff so should be ez next time. Did 5x amber, macros were as follows:

occulus1:
#showtooltip
/target Ley-Guard
/cast Shock Lance

occulus2:
#showtooltip
/target Ley-Guard
/cast Temporal Rift

occulus3:
#showtooltip
/cast Stop Time


I put occulus1 as #1 button for char 1 & 2, and as #2 button for chars 3, 4, 5. I put occulus2 as #2 button for chars 1 & 2, and as #1 button for 3,4,5. I staggered occulus3 into button 3, 4, 5, 6, 7 -- so char1 had it in 3, char2 in 4, char3 in 5, etc.

I just ran up to the last boss, hit 3 (timestop char1), and just pressed 1, 2, 1, 2, 1, 2 with a 1 sec pause in between each key. Every time timestop was over I'd move to the next one -- 4, 5, 6, 7, 3, 4, etc. Boss was down in under a minute, just run away when he phase shifts.

Got a TON of scarlet ruby and other blue gems (awesome for alchemy xmutes!), 2 extra frost badges, and a single mount in one of the bags. Definitely worth it!
