PvE:

MUST HAVE:

Flame Shock
Lightning Bolt

CHOICE:
Lava or Flametongue (Both almost equally good, if you like big numbers and are comfortable with your current crit go lava, if you're a bit low on crit as it is go flametongue.)


PvP:

Flame Shock
Lava Burst
Shocking



5x shaman or 4x shaman but somewhat starting gear for 5 mans
Flame Shock
Lightning Bolt
Healing Stream



These are my opinions and though based on some pretty good experience, different playstyles could still allow for different glyph set ups.
