Pros/Cons of each Marauder build

In my opinion, 21 Blast is the best way to go. I don't see any use for it past 3rd job because Dragon Strike is so much better. Shockwave is the only mob attack in Super Transform so I don't see why it shouldn't be maxed, especially since S-Tranform's cooldown is technically only 2 minutes.

Besides, Shockwave gains more damage per hit with those 9 SP than Blast. Shockwave at level 21 is 565% and maxed is 700%, which is a 135% improvement. Meanwhile, Blast at 21 is 366% and Blast 30 is 420%, which is only a 54% improvement.
