The allies system ruined 40k I really don't want a system like that in x-wing.
40k was ruined by more than just the allied system. Besides that system used an unbalanced grid where some factions have no friends it was focused on theme rather than balance. A wheel system would be way better.
Besides I didn't see that many multi-codex armies when allies came out. It was still a Space Marine army had Space Marines and a Dark Eldar Army had Dark Eldar. There wasn't much faction mixing in 40K in 6th edition when I left.
