That was from sustained until OOM, however it was inflated due to clipping of 2 other dummies with Living Bomb. I have also modified my spec and Glyphs since then, removing Combusion, and adding Arcane Meditation, due to mana issues.

I'll post a WWS on the 83 Dummy with my new spec. The DPS will be lower, but the fight will be much longer, and better indicative of my performance in raids. Please note that I am not hitcapped without a Boomkin/SPriest currently, as I used to raid as Frostfire Bolt, which used to double-dip from Elemental Focus.

My Hit is current 372, or ~14.1%.

This test:
Was focusing on the 83 Dummy
Clips 2 80 Dummies with Living Bomb
Was done going through Evocation, 2 Mana Gems, and Arcane Torrent. This cost me a Hot Streak when I was <1000 mana.
5x Scorch, due to no Scorch Glyph, Imp. Shadowbolt, or other Mage.
Missing Focus Magic (3% Crit)
Missing Torment the Weak (12% Damage)
Arcane Int. and Molten Armor only.
I was the only one attacking the dummy, besides a Warlock Drain Soul-ing.

Approximately 3.0k DPS on the Heroic Dummy alone, once Living Bomb clipping is removed.

I have no WWS Reports of these, but I had 3.9k DPS on Emalon and Sartharion, without ignoring the adds, or eating Flame Waves.

EDIT:
Picked up a large upgrade in the Greatstaff of the Nexus, my Armory will look strange, as Maintainance occured whilst I was swapping around gems and enchants.

Good luck on your new guild, Thai!
He is a really good player and I'll miss him.
