I think Bossk is ok but putting two focus on him is a big hit to your tempo. Bossk is not elite so you lose him the turn he comes into play, then two more turns after that and then you have worry about tactic icons completely locking him out. Sure, you probably took out a main CHARACTER but you just lost 3 turns yourself. Another thing to realize is that it is characters only, so if vehicles become any more popular this guy isnt that good.
Jabba's Reach will be a super sick objective if a few things happen
A. Capturing is super easy and you can put captured cards to this location.
B. It is easy to keep this objective in play
C. You can move captured cards from the Jawa's objective.
Multiples of Jabba's palace will be pretty good, especially if you can get multiple cards captured at them. I have high hopes for this objective but I am afraid that its going to be far worse than we hope.
I think Jabba is going to be better against vehicle decks more than Jedi/smuggler decks, thats not to say he will be bad against Jedi/smugglers, just that he will take far less damage on average against vehicle decks than character based decks. I am anxious to see how good his ability will be, if they have some sick enhancements then Jabba will be so much better.
I think Slave 1 is going to be a little overhyped, but that depends on some things.
A. How easy is it to capture cards. We have already seen the Jawa objective so thats a possible automatic 2 captured cards.
B. How long you can keep those captured cards captured.
C. Can you move captured cards around
Also, how easy will it be for the Scum to get to 5 resources and how will they fair in edge battles. 5 resources is a lot to spend on a 3 health unit that is not elite. Sure, you might blow up an objective with Slave 1 but will it survive the engagement.
