Just now, Darth Meanie said:*sigh*
There could be at least 10 ways to do this:
1. Require Vader in the list.
2. Only allow the BHs we see on the bridge of the Executor.
3. Require them to be "hired" costing list points.
4. Require the to be hired using a mod/title slot.
5. Not allow more than 1 per list.
6. Create them as a new pilot card that is Imperial only that gets used when they cross-over.
7. Make that cross-over card different/weaker than the S&V faction card.
8. Make them "casual only."
9. Use the All Hallowed App to fix any balancing problems.
10. Just do it because it would be fun and f*ck gameplay just once.
I’m not saying there aren’t ways to make it work, but that takes more thought and consideration then just flipping a switch. And once you open that flood gate, more problems could arise.
Also, your 8th option doesn’t need FFG.
