Battleship

I don't get it. What's wrong with Band of Thieves. It betters with progression.

Level 18: MP -30; Basic attack 180%, 3 "other selves" will attack enemies
Level 19: MP -40; Basic attack 140%, 4 "other selves" will attack enemies

You tell me which is better, 4 target mob skill for 720% damage total or a 5 target mob skill for 700% damage total (assuming you hit 5 mobs, which happens less often than hitting 4. It happens at other skill levels, but level 18-19 is the worst deal ever.

Same with Spear Crusher when you move from

Level 15: MP -16; Basic attack 120%, attack 3 enemy 2 times
Level 16: MP -19; Basic attack 124%, attack 1 enemy 3 times.

Battleship doesn't hit certain levels that are better to skip, though. It appears that it simply gets worse.
