I'm going to go out on a limb and suggest that every single pilot, secondary weapon, crew, and whatever else is released for Wave 5 will entirely and utterly...
destroy
ruin
off-balance
over-power
kill
be over-costed
be under-costed
... the game and otherwise give the Rebels and/or Empire everything they need to make it completely impossible to successfully use the Empire and/or Rebels EVER AGAIN.
There. I've ninja'd all upcoming Wave 5 posts.
Or... we wait and see what's coming, adapt our strategies and squads, and keep riding this awesome and fun rollar coaster that is X-Wing. So far, at least to me, FFG has done a spectacular job of balancing every release once we see it all at one time.
