Or its "you may assign one focus token." The assumption we're making from the article is that its the advanced cloaking device that allows re-cloaking after firing. Whisper having an ability to re-cloak without the advanced cloaking device would make him an ill fit for an advanced cloaking device (better to put in a recon specialist and stealth device instead) but the article mentions it as a good choice.
You have a point there.
Now that I read the spoilersetup better, advanced cloaking does seem to read "after you perform an attack, you may perform a free cloak action".
Then, judging by the phrasing and available space, I think that Whisper will read 'gain 1 focus token' because it would not make sense to remove a focus token from a target you just hit, chances are that the token was used anyway after all. (I don't think it says 'assign', there's not enough space to specify who you may assign the token to including range text)
Running Whisper with ACD, Elusiveness or Expose might be interesting. Decloak, rush up to R1, Expose for an attack of 6, gain a focus, recloak and still have an average 3 agility plus a focus for defense in case you are in someone's arc.
And now that I write this out I'm curious why FFG would then choose to give Whisper a focus instead of a straight-up evade token, it's not as if the focus will be used for anything other than defense, will it?
Now I'm confuzzled.
