So if you cast this, the problem is you just wasted 2 full seconds (1gcd+1 tremor recast) to shield yourself for less than a second, not to mention your tremors will no longer be staggered. That's essentially like standing there doing nothing for 1-1.5 secs. That time is much better spent rotating thunderstorm or healing.
And yes lightning bolt glyph is a raiding glyph for long duration rotations. Not gonna buy you any kills with it.
This is in my guide which is almost complete, but the best 3 glyphs are lava, shocking, and thunder... with TOW being a decent 4th option in place of shocking or thunder (shocking is a must for arena tho).
