It works like a TIE defender without any of the other titles nuff said
Well the other way of making it work is shield upgrade and regen. I have seen the earlier build with (prenerf) bigs that take draw their fire but that won't fit in a list with Aztec gunships. I have also seen sensor jammer in conjunction with regen. Makes it tough to kill but now that focus can be automodified that is not going to work. Expertise has pretty much killed sensor jammer.
