A few things. Mastery is > int for tendon burn. It's a 1.6 to 1 ratio in favor of mastery. And the other thing is that rotation/macro will not yid the largest result. I'll post more on this when I get home but the rest looks fine for now.
kk, so this is the macro I've been using:
/tar boss2
/stopmacro [noexists]
/use 14
/cast mind spike
/cast [target=boss2] mind spike
/tar boss2
and this after my second MS as explained after:
/cast Shadowfiend
/cast [pet, nomodifier] Shadowcrawl
/cast Berserking
/cast Archangel
The macro you made cast AA with no target avail. So the second you hit that it casts AA. This one allows you to spam it w/o a target and not waste and cd usage. Now if you cast it as early as you have, you will not get the AA dmg buff for the last MB which is where most of your dmg comes from.
Basically what you want to do is spam this twice get to MS off cast fiend, then mindblast with 3 orbs, ms 4 times wait that .5 seconds to MB so you have 3 orbs ms 3 times mf 1 tick and mb once. With this rotation you get 3 MBs with 3 Orbs each.
What you want to do is go to wowreforge.com set mastery to 10 haste to 1 crit to 5 and hit/spirit to 9 this will give you the best dps for tendons possible. The dps over the rest of the fight will be low but you should easily be doing 140+k a tendon. For trinkets the best results I've gotten were moonwell chailce/bottled wishes these two can be easily interchanged depend on what you have at your disposal and heroic NFC. To keep NFC you want to dot like 4-5 bloods before you kill the Amalg. This way with sw
rolling on the mobs it keeps your mastery stack up the whole duration and it keeps the possibility if you ever get a spike w/o orbs to possible proc orbs.
