1% increase every 3 days for something that is already a chance occurance doesn't beat 12 turns of stockpiling. Booms could be slightly better than a stockpiling turn, but I'm guessing they are toned down from the previous changes, and I tech.

I also play demo, so I don't bother with missiles. Only thing luck is really useful for is to secure higher land rates, but it's prolly too low to be worth it that early.

Although pang has hinted at how awesome it is...
