I've had my wave IV ships since the day they launched, but so far haven't had the opportunity to play with them yet.. I've played with some builders but that's really it so far as I just returned from a 3 week vacation.
What I seem to see a lot of though are people pairing Echo with Veteran Instincts. Why? In the few lists I've come up with, I just don't see the value when compared to some of the other options that are available like Outmaneuver, Push the Limit, Predator or Opportunist?
I understand that you're hoping to shoot first so you can recloak right away (with Advanced Cloaking), but beyond that I see it as a wasted opportunity. .
