Hopefully the next wave(s) will make this redundant, but Vinto and Elite Weequays seemed pretty much ubiquitous at the top tables at Worlds, suggesting that they're a bit too good. There were plenty of other popular Mercenary units but Vinto and Elite Weequays seemed compulsory (I certainly didn't regret using them).
So I had an idea to give them both a new negative ability.
Unexceptional: You cannot become Focused.
It gives them a (hopefully small) nerf, without really changing the way they were designed, and as an added bonus reduces the incentive to include everyone's two favourite Rebels. Probably not enough - we'll just see Greedo or Onar or Gamorreans focused instead.
On an unrelated note, I think it would be nice if Fury of Kashyyyk had a negative cost given the usefulness of Wookiees in skirmish.
