@Eph, glyph choice is obvious, spec choice wasn't. I was replying to someone that said "spec incin". So thanks for your thoughts on Bane.
on another tangent, I'm finding that normal SB-demo spec sims within 10 DPS for me, on a 300 sec fight (i.e. H zon'ozz and H ultrax) with several trinket choices (all will of unbinding + w/e). On longer fights the number of extra metas you can get out of incin spec without syncing meta + DS prob. takes the advantage, but you get 4 metas with either spec at around 2k haste, with dragonwrath for extra impending doom procs, on a 6 min fight. Will sim again and make another post since I just got some upgrades that allow me to get more mastery and less haste.
unrelated: just updated my insta-felhunter macro to do:
/cast [nomod:alt] soulburn
/cast Summon Felhunter
/petattack
Now my felhunter always shadow bites my target the instant he's out, and I don't have to spam another button that has petattack macroed. Now watch me replace moonwell and stop pet twisting on most fights... :P
I have noticed that my felguard will often fail to legion strike after felstorm is over. It is set to autocast. Manually clicking it before hitting my insta-felhunter, after felstorm, does get it to cast. I'll test next time I'm on putting /cast legion strike before summon felhunter in my soulburn felhunter macro.
edit: of course when I go to test this on a target dummy, it legion strike casts fine after felstorm ends. Often not the case on boss pulls in raids. I sometimes watch for legion strike going on CD to know when to consume soulburn with felhunter during my opening rotation, and it doesn't always happen, even when the CD on felstorm is down to 37 seconds. (it should end at 39 secs left, 45 - 6 = 39)
