He's in a weird spot, because his draw is action economy, but Vader does it better and at 4PS higher.
Vader has good action economy while unstressed, unblocked and during the activation phase.
Alozen has good action economy when winding up at Range 1 of an enemy, irrespective of when that enemy gets into Range 1, even if he is stressed.
Vader's high PS works to his advantage when deciding which actions to do, but he gets blocked by every single pilot in the game, and becomes just a level 9 Tempest (with EPT).
Now that I think on it, Alozen is a pretty good choice for Enhanced Scopes. He gets to save a Target Lock for the start of combat step. Turn him into a blocker whose actions are guaranteed...
