The Eagle must indeed be worth significantly more than a Queen. (Although in the late end-game its advantage would disappear.) But you would use it to attack the King, which is worth the game. A Terror would probably also be more valuable. You would not waste it on any lesser piece.
Dababbariders would not be dangerous for a King hiding behind 4 rows of pieces.
