Prior to getting my wave 2 goodies, I thought Ozzel was the bomb. Unpredictable movement, rapid stops/acceleration in/out of firing arcs, and cheap.
Tried him on the table and he was complete garbage. You use that special ability only once or twice per game max. Usually your star destroyers are going full tilt anyway to get into black dice range. Dano hit the nail on the head - all the other Admirals give you something through the game (tokens/shooting/hull) without requiring lots of work.
Maybe I just had the wrong list or didn't fly him right, but I think he sucks.
