I'm pretty sure there's something fishy going on with Rawr. Last night I finally got a long-overdue weapon upgrade (which put me horribly over hit cap), so I decided to fool around in Rawr/SEIC to help decide between glyphs (again). I typically look at Rawr's relative stat values to give me an idea of where I'm at for valuing haste vs. SP, but I found something pretty weird.
With Rawr's top 3 listed glyphs for my gear (LB, Lava, ToW) here are the relative stat values.
Same 3 glyphs, but using SEIC:

(note that the CL after LvB or the no CL rotations have crit being worth even less relative to haste)
The odd thing is that if I use the glyphs SEIC suggests in Rawr (FS, Lava, LB), then haste pops back up above crit (though not by much - haste = 2.54 DEP, crit = 2.19 DEP). The reason this is odd is because I would have thought that the glyph of Flame Shock would make crit a more valuable stat than the glyph of ToW or (especially) the glyph of Lava.
A possible explanation:
When I throw in the Glyph of Lava, crit shoots way up. With FS, it goes back down. When combining the glyph of Lava with the 4t9 set bonus, LvB becomes quite powerful. I'm guessing that the increased value from crit stems from Rawr not taking into account that it has a 100% crit chance from FS when calculating glyphs/relative stat values. The reason this problem probably exists is because of the 3.2.2 Flame Shock change, since the glyph seems to be the reason crit is devalued with the Flame Shock Glyph. Without the FS glyph, I suppose it's still calculating it with the LvB consuming the FS.
