Everyone's had a bit of time now to ponder the new wave and for me I think it's going to be a **** of a meta shake up, the like of which we haven't seen since the release of flotillas.
The main thing in my mind is that we now have a critical mass of solid squadron defence options that can be placed on ships usefully, playing in a high squadron meta and since Maarek/Jendon appeared I've basically felt full/near full squadrons to be compulsory because there just wasn't enough good defence options. Between the new ship varients, early warning systems and cool little flak options my hope is that will balance out and you can afford to not run heaps of squads if you want. Even just the addition of a simple strategic officer is a points effective way to avoid having to play the flotilla war. All really awesome stuff!
I think the best thing about this game has always been the variation of possible effective builds and this wave just adds to that. Never played X-wing but it seems the players there never stop complaining about the latest uber build for about 3 weeks before some sweeping errata nerfs it and the cycle starts again... so glad our game just doesn't have that.
