Bastila Leadership Zeta?

If you don't have Palpatine's lead yet then you should do it immediately, it might be the most transforative lead zeta in the game. His unique is much less important however. Also if you have a lot of sith then Darth Maul lead zeta is very worthwhile, very good team on both offense and defense, but only do Maul if you have enough sith for a Palp empire team and a Maul sith team. Bossk lead zeta for bounty hunters is also incredibly good. Jango's is arguable better for pvp, but Bossk isn't far behind and he's much more versatile. Oh and Nightsisters. They're another strong early accessible team that you might want to build towards.
