Sith situation is out of hand

I don't think Zaul is overpowered, he's just easier to get than others. There are numerous top teams right now, and Zaul is just the easiest. A good QGZ team can beat Zaul, but that requires two zetas (QGJ and Yoda) and GK, the toughest character in both gear and shards. A good First Order team can also beat a Zaul team, but it requires three or four zetas. Even a good Wiggs/Chaze team can beat Zaul, but Baze is incredibly difficult to farm and the fifth character is typically Kenobi, the most difficult character to gear and farm. Compared to these teams, a Zaul squad requires only a single zeta (Zaul, Zavage helps but is optional) and both Nihilus and Sith Assassin, two of the other members of the Zaul squad, were recently gifted to the entire player base. Zaul squads aren't actually any better than QGZ, FO, or Rebel squads, they're just much easier to obtain and just as good.
