That an the bulk of the advantages that buccaneers have as a class is invincibility which is even more of an asset in supreme, but that is completely invalidated by cooldown.

Well, not necessarily invalidated, it just means it requires a lot more skill to time these skills. The main problem right now for Marauders is the cooldown time of the skills.
First and Second job skills have a 5 second cooldown (e.g. Sommersault Kick, Corkscrew Blow). The Tornado skill is semi-useless since it's ranged and therefore has a high miss chance.
Third Job skills (Landlubber Blast, Spiral Assault and Energy Blast) have a 10 second cooldown.

If your Energy isn't charged up this results in a lot of normal attacking or trying to be smart and jumping over mobs usually resulting in certain death.
