Next Update Sneak Peek

Eh. I made a table. DrKs have HB here, I left out mages and Buccs for obvious reasons, I neglected to factor in buffs, and I didn't include Snipe for MMs since it costs like no MP anyway. All characters are levelled with 10 int from level 10 - most people should have more (I've got just under 4k MP at 154, a lot more than the 34xx I should have), or slightly less if they're washed to minimum. This basically shows which classes burn the most MP with their attacks, relative to the size of their MP bar. Time is the amount of attacking they could theoretically get in. All classes are using regular speed weapons (I assumed Normal (6) for Swords/Slow (7) for Spears/PAs) and Booster.

Class	Skill	MP/s	Total MP @150 w/ MoN	Time (s)
DrK	Crusher	24.2	2190	90
DrK	Fury	26.7	2190	82
NL	TT	33.3	2644	79
Shad	Bstep/SB	37.6	2644	70
BM	Hurricane (with Conc)	41.7	2644	63
MM	Strafe	44.4	2644	59
Corsair	Cannon	63.5	3344	53
Pally	Blast	32.0	1369	43
Hero	Brandish	33.3	1244	37
BM	Hurricane	75.0	2644	35

Oh, and don't forget mages have bigger issues with MP than skill cost. Magic Guard eats a huge chunk.

Fury should be assumed with a slow (8) weapon, as most polearms are 1 speed slower than spear counterparts.
