Great map. A couple of things:
People complain about lag, but heck, they do the same in my Theramore Arena, and it probably has less triggers running, so... can't be helped, I guess.
Not sure about this one, but it should be easy to look into. I ran over a bomb buoy, when the guy who planted it was nearby on low hp. He killed himself, and I think he got a kill for it. There should be a special message for such a situation, and the suicider should get no kills/loose a kill.
Also, you should record a new "not enough mana" message, with a pirate's voice, for extra atmosphere. :)
Cool map, approved.
