What good number? What for you a good number? Cause honestly 5/5 Hyoton with Futae go between 950-1250 easily and sitgly more in abyssea w/o MAB atma or specific gear beside Iga +2 set. I'm sure I can boost it up easily with few gear, and Tsurara are so cheap to make/buy... Add the fact than Hyoton: San recast is 60 sec w/o fast cast and Futae is 3 min.

In other word, beside RP, Shuriken and Sange can't even catch San spell. Add on that that San spell HAVE utility VS high resistant melee mob and those are usualy weak to magic (ninjustsu). You want good number? build a magic attack set and go with Ninjutsu instead, you wont catch melee but at least, you would do some decent number at lower cost.

Also, the "I pay to play so I can do anything" isn't a good argument to prove you're point.
