I keep seeing people say Fire Ele scales with haste. I did a few simple tests (will do more when time permits).
Tests were on Org heroic dummy, using Skada. (I know not 100%, but its a rough estimate)
Naked:
Fire Nova: 29 hits, 3 miss
Attack: 12 hit, 7 glancing, 3 dodge, 1 crit, 3 miss
Fire Shield: 66 hit, 2 crit, 12 miss
Fire Blast: 12 hit, 3 miss
Naked +BL + Berserking (troll racial).
Fire Nova: 24 hit, 4 miss, 1 crit
Attack: 16 hit, 8 glancing, 3 dodge, 2 miss
Fire Shield: 65 hit, 4 crit, 11 miss
Fire Blast: 11 hit, 4 miss
Geared: ~ 15% haste, 17% hit, 20% crit
Attack: 23 hit, 11 glancing
Fire Nova: 24 hit, 1 crit
Fire Blast: 14 hit
Fire Shield: 75 hit, 5 crit
Geared with BL and Berserking
Attack: 22 hit, 7 glancing
Fire Nova: 31 Hit, 2 crit
Fire Blast: 14 hit
Fire Shield: 73 hit, 7 crit
It doesn't appear to be any scaling with Haste or Crit. It does obviously scale with spellpower, and is a Snapshot of your SP when you drop the totem.
This is a small sample size obviously. RNG played a factor, but I would have expected significant differences with BL+Berserking if it scaled with haste.
Something I also want to test is if Fire Elemental scales with the +dmg part of EM.
*side note*
Something should be said about Fire Elemental in the ele guide. It is a pretty significant part of our class and not much besides keep fire totems down is said.
