Arena will want a different set of glyphs.
Glyph of Shocking is probably required, and Fire Elementals are not usable.

But for world pvp, BG's and pve...

Totem of Wrath glyph grants a lot of spell power.
As a 5 min buff, which means we can then drop Fire Elemental and keep the Glyph benefits.
I'd probably still have one team member leave ToW down.

Fire Elemental glyph brings us to 5 mins for F. Elementals.

Lava Burst glyph is more damage on our big spell.
Elemental Mastery knocks 30s off of our almost-instant kill spell 2.5min/3.0 mins = 5/6 = 1/6 faster = ~16.67% reduction in cooldown.
Lightning Bolt glyph is a slight improvement to our bread and butter spell.

Still a few choices.
