The only difference is that you’d be forced to hold off one turn. No biggie. 5 Bombers is 15 IPC you’re down anyway, and since it’s going to take at least a round to get into position, waiting 1 round for units to save up is nothing.
BTW, the Flames dicey is screwed up on rolling the damage. They say attacker does 3 all the time, defender does 2 or 3. I already notified them it needs to be fixed to come into accordance with the actual description of LL SBR.
