The Bantha strongly depends on luck. If you don't roll well on your Tramples and don't draw the right command cards, the Bantha can be a sitting duck. Therefore, many good tournament players don't use the Bantha for it's inconsistancy.
But chances are higher, that you draw at least some of the right cards, and roll an average of 2 1/6 damage.
My last game against a Bantha was a mess.
My opponent had Dev. Schemes, HKs, Beast Tamer, Bantha, Gideon and all that other good stuff ...
It was on Constant Motion (Obi-Wan / Anchorhead is not released in Germany by now). I had to go for the droids, or else I would have lost anyways. 2 HKs hiding behind their deployment zone's corner made that hard anyways. The HKs scored 4 points, while I managed to keep out of range of the Bantha. Or at least I thought so. Gideon moved the Bantha for 2 spaces and used Planing. Last activation on turn 1 the Bantha moved 17 spaces (Beast Tamer, Urgency, move) and stampeded 3 of my figures. Then he had Jundland Terror, stampeded 3 figures again and then trampled them for 2 damage each. Then he had Ferocity. Then start of turn 2 (I didn't draw Take Initiative) the Bantha moved with Beast Tamer to stampede 4 figures (the Bantha had pushed them together with his other Stampedes), Crush one and then used Single Purpose to trample twice (3 and 2 damage on 3 figures each).
First Stampede = 3 damage, Jundland Stampede = 3 damage, Jundland Trample = 6 damage, Ferocity = 3 damage, last Stampede = 4 damage, Crush = 4 damage, Single Purpose Trample = 9 + 6 damage.
The Bantha moved 21 spaces on turn 1. He caused 38 damage to score lots of points 'til the first activation of turn 2. Because of the Bantha, my opponent was able to score 2 droids, which is another 8 points. (I was able to score 1).
I quit with 28:4 points. Fun, strategy, tactics = 0. We just set up, the Bantha moved in, game over.
Passing fixed some problems with the 4x4 and made 9Act obsolete. Nerfing Officers and Royal Guards made 4x4 obsolete. The new Tournament Rules fixed the Trooper-Spam / Reinforcements problem. IG-88 will be fixed soon, too.
Now, FFG, please fix the Bantha/Beast Tamer. 4x4, 9Act and Trooper-Spam combined were not as stupid as this Bantha. Have you seen the Banthas in the movies? Do you think, they seem to be faster than a Speeder and hit harder than Vader?
