Alternatively, as mentioned, Brawler 5/Sawbones 1 gets it too, and multiple attacks per round. Quite a few get access to Tiger Claw for free TWF multi-hitting, and yes, that ability is open to all of them. It's basically "give up 1 BAB for +5 damage permanently".
Which is a bloody awful trade for an E6 game. You'd never get your second attack per level.

As far as Fireball goes however, it's not a "good" spell because damage isn't a good use of a mage's time. In terms of damage it's absolutely dead on with multiple targets, 6D6 damage. Remember that's the same as a mage's hitdie, so you're potentially into instant kill damage against any E6 character who rolled poorly on their HP).
There are many instagib combos in E6. Fireball isn't a good one. Try Sudden Maximize, Sudden Empower Enervation. No save, just die for any of these classes. All for the cost of 2 feats. Or really pair that with any large damage spell. Dominate Person. Save or you're ****ed. The dragon gets unlimited 6d6 attacks in the form as breaths.
