BUT, You also forgot to mention that Terrafication raises the target's Defense and Mana Defense, which means Exp would be lower still, Blockage has no affect over defenses, and only lasts for 2 turns, so basically, its quite useless to burst like that with non reborn fires =/

Yes. Terra and Tree Bind both do that, right? So Earth has no bind/debuff that doesn't hurt exp?
I haven't actually done any bursting, but I'd think Earth would want something like...

Stone Wall on pet
Stone Wall on self
Blockage
Scurry Beating

Maybe substituting Shield Defence for Stone Wall to save SP?
But again, I haven't actually tried.
