I've been toying around with various Imperial builds trying to incorporate the Wave 4 ships and upgrade cards. If I include a Phantom or Defender, I usually end up with a 3 ship build (excluding howlrunner mini-swarm). Although the 3 ships are decked out, it's still only 3 Imperial ships (i.e. squishy). One caveat is that I'm using the named Wave 4 pilots, but the non-named pilots can be just as expensive. So my general comment/question is that will the imperial meta shift towards 3-4 ship builds instead of the 6+ ship swarm? If so, would it be "tournament" worthy? One build I like is:
Fel+PTL+Stealth
Echo+FCS+VI+Adv Cloaking Device
OGP+FCS+Tactician+Gunner
