Hello,
I was able to solo H Stoneguard 10 months ago with 568 ilvl and BrM spec. Consequently, this is clearly possible with your gear.
Just a few tips for help :
Talents used were Tiger's Lust / Chi Wave / Ascension / irrelevant / Diffuse Magic / Rushing Jade Wind. Glyphs were Guard / Enduring Healing Spheres / Fortuitous Spheres (the 3 strongest glyphs for soloing in most of the situations).
About the encounter, it's a funny mix between DPS and Survival. DPS must be at around 500k to beat the enrage, but it's possible to squeeze a few seconds upon the enrage at the end. Now, there's two tremendously important points :
1) ALWAYS keep running while activating the squares on the floor. Iirc I had 100 stacks for the first fade out, 130 for the second, and 100 at the end. The more you have, the more damages you will deal. Making a rotation of speed CDs (nitro boost / Tiger's Lust) is essential. Also, use these speed CDs at the lower rate of petrification as possible. The more the bar is full, the more you'll be slowed.
2) CDs are timed. Never use them as reactive abilities.
How to perform the CD rotation :
1st explosion = DM
2nd explosion = FB + Avert Harm
3rd explosion = DM
4th explosion = roll => ZM
5th explosion = DM
6th explosion = FB + AH
7th explosion = DM
8th explosion = ZM
9th explosion = DM
10th explosion = just Guard and keep FB + AH to squeeze DPS on the enrage
if you can beat the enrage, just use FB + AH on the 10th.
Then, your glyphed Guard must always be up for the explosion. Just play with timing.
Not that much to say. With 568 ilvl, I encountered 245 wipes (always around 10% enrage - boss ends at 1.5%).
This boss isn't that easy. Best of luck

Theorically, everything in BWD and BoT 10 man normal should be possible with 553 ilvl as WW monk.
Actually, when I did a shot, it was all feasible with 463 ilvl and BrM spec.
Cho'Gall and Nefarian may require a tank spec though.
