>Amph constructor doesn't have a special ability (apart from being amph).
Freaker has no special ability (apart from jumping).
Weaver has no special ability (apart from crawling).
Hover con has no special ability (apart from floating).
Crane has no special ability (apart from flying).
Mason has no special ability (period).
For Freaker vs. Amph con: both are just fancy move types. One can go under water, one can go over hills. Makes for a poor argument, imo. Freaker being able to rez just FITS. It's a special ops unit that can sneak around and rez enemy units! How cool is that?!?
