Elemental in challenge modes

[Galaen]

Hello

This weekend I shall be venturing into my first serious attempts for challenge modes. Now I want to ask experienced elemental shamans for handy tips on the dungeons and what glyphs/talents are best!
I usually roll most my time with flame shock, unleashed lightning and CL glyphs. As talents I use astral shift, earthgrab, totemic projection, echo, ancestral guidance and elemental blast.
Should I change this setup for some dungeons?

Thank you!

It depends on the instance really. I recently put out my CL glyph, since there are occasions where its a dps loss (2-3 mobs), only really helps at 4-5 mobs.
Also I like primal fire elemental a bit more than elemental blast, since it gives you more burst with bloodlust and in short fights. Plus unleashed lightning glyph only helps on fights, where you HAVE to move almost constantly, which is almost never. In most fights you have enough stuff to do when you are just moving for a bit like lava surges, shocks, searing etc.. it's only 5% less on LB, but hey, every % counts in challenge modes.
