Empire team with no ST?

Right now, I'm running Zoba (L), TFP, Palp, JKA, STHan, and finish top 10 in an early April shard (sometimes top 5). I do plan on transitioning JKA to Shore and STHan to Rex (and Rex to lead), as I finish gearing them, but the key is really speed -- my TFP is faster than most people on my server, and my Boba is getting up there are well. Also, even if Palpatine is killed before he can go, it leaves the rest of a dangerous team out there.
