Theyre afraid of him because of doubletap and nothing more. Even in his absolutely horrible ship, if he can get in the right spot he can decimate a ship very quick.
That being said i too think hes a pile of crap. Only once ever been owned by him, and that was the first time seeing him. Hes not hard to remove from the board given his predictability and 2hull. Killing him with a single proton bomb is so awesome...
