Elemental Weapons Are Glitched?

To add to the quoted post;

F/P & I/L's Ultimate has a 570 base Spell Attack.
After Amp, it's 770, with a 7,000 MP cost.
After Elemental Staves/Wands, it's 962, with 7,000 MP cost.

Bishop's Ultimate has a 670 base Spell Attack, with 3,500 MP cost. No Amp, No Staves.
Having just over two thirds of the power and half the cost is much more reasonable than having almost 90% the attack power, with half the cost. :[

Also, skeles are weak to holy and newties are not weak to anything lool.
