Glyph of Stoneclaw totem

[Otlecs]

I've seen this mentioned in a few threads, and I've brought it up myself, but I'm really agonising over the decision as to whether I really want to use it now I'm closing in on being more useful in PvP.

It was a no-brainer for my resto spec - I didn't lose anything useful - but it's tougher for my elemental specs.

At the moment, they each use Glyph of Lava, Glyph of Lightning Bolt and Glyph of Flame Shock (sorry, no item tags there because it just makes the text unreadable).

I DO struggle to stay alive against more than one whirl-winding warrior, even with instant GW to bug out, so I could definitely use some more survivability, but I don't know which of the existing glyphs I would drop.

So, for you more experienced PvPers.... could you tell me if you use this glyph, and what your thought processes were in deciding what glyphs to actually run with?

Thanks in advance.
