Actually Panic for a while there, HLBC allies were so cheap that you could increase your BFA by dropping the grossly overpriced ones from the t4 era. For example, I dropped a 700 bil ally that had 8.5 mil combine stats, got about 400 bil back, and bought a new ally with 12 mil combined stats for 350 bil. My bfa increased and I still had 50 bil to spend. This, of course, was a few months ago. The market has changed a bit since then.
