Jump Jets won't really help Boba too much, since (1) he already has Mobile (ie, flight for the SWM player), and (2) it requires an Action to use and he already has Speed 6 himself (so why would he spend an Action to move just 5 instead of 6?). Jump Jets will be awesome for Vader or Chewie (big pieces with slow movement), but I really can't see a purpose for it with Boba.
And yes, Boba with a Protector is a total beast...2 automatic Blocks (ie, damage reduction) and 1 automatic Evade (ie, surge-cancel), plus whatever he happens to roll with his Black defense die. He's pretty much equal to Vader with those defensive abilities...and he can Recover!
And don't minimize the value of that automatic Evade...it makes it much harder for your opponent to get those crucial Stun or Blast or Pierce effects. I've found that he's often the last guy left on the board, just because he's so hard to get damage on.
He's not a heavy hitting glass cannon...he's more of a tactical ace with plenty of tricks up his sleeve. Seriously, he's my favorite piece in the game so far...and this is just speaking from a game mechanics/tactics standpoint. My kids are always fighting over who gets to use Boba Fett! lol
And Mandalorian Tactics...let's just say that there's a reason this bad boy costs 3pts!
