I'm prepping for a major tournament and had bought 3x Expertise on ebay to use a Wookiee list because I'm too lazy/busy to playtest anything and I'm a dirty netlisting can't-fly scumbag (no offense to the actually good wookiee players out there) but then I see that the list has evolved to replace the 3rd Liberator and 3 Breaches with Lowchuck and Predator + 3PO.
I understand that that there is a slight defensive boost in being able to get an extra evade per turn either through 3po or Loschmuck's ability, but is that the only advantage? Also which list is better against Poon missiles? One reason I liked trip Liberators is because they don't have to fly at range 1 of each other. Please help, I am noob.
