Changes that would make your class more fun.

Double Spiral being able to aim in any direction. e.g., if you press up and Double Spiral simultaneously, your character will rush up to the platform above you if there's a monster there. It would give Buccaneers more mobility and make them a bit more interesting to train.

Mechanics have portals. What we need are good, old fashioned, ropes.

Buccaneer:
Rope
-Master level 5
-Throws a rope that sticks to a platform above you. Rope lingers for 20*slevel seconds. Additional 20*slevel % climbing speed when climbing rope. Allies can use your rope.

Instead of a rope, just make it an anchor. Awwwww yeaaaah full circle.
