Sorry if thread-hijacking, but do you mean 2.0 or something else?
DW Fleet Action was more of a companion game instead of a full edition like 2.0 or 2.5 that was a cut-down set of rules that was supposed to be quick play just like the quick play Spartan put out for Firestorm Armada - Firestorm Taskforce.
Both Fleet Action and Taskforce were under 40 pages, and I prefer FA Taskforce to regular Firestorm, but I don't know how quick games with DW Fleet Action would have turned out. I checked back through my copy and there were still 4 altitude bands for models, but my interest in DW then and now was only to see what mechanics Spartan would carry over to the next build of Firestorm Armada.
