Can the various pilots/ships be categorized in terms of offensive, defensive, and/or utility? For example, wedge as offensive, Biggs and Luke as defensive, and Roark as utility?

Some would be hard to define since they could be used offensively or defensively depending on the rest of the list or the opponent and what stage of the game it is. Also why would you need to provide a list of this?

I would think another category would be mobility.

How would you define soontir, since gaining a focus can be either offensive or defensive?

Also since Roark only ups your ps in the combat phase isn't he also offensive?

Carefully define your catigories, based on the rules. Try to capture all off them in 4-5 categories and it can be done and still be useful.

Also since Roark only ups your ps in the combat phase isn't he also offensive?

I would say anyone whose ability effects other ships in your force is support. I suppose you could define offensive support and defensive support, but that seems like too much division to me.

How about just divide everyone into Bad a** (Baron Fel, Keyan Farlander)
