I wonder how much the heavy weapon will make a difference in if they are worth it? The cards show one that is range 2-3 (I think) and the other has three red dice.
I also wonder if this unit is more of a long term plan. They may not work now because of how expensive everything is now, but if CIS does get a cheap commander and a few other cheap units to throw in then maybe upgrading a few B1s into B2s will not matter in a 12 activation list???? They did say in the Q&A that anything over 12 activations sort of stops being helpful......
