If the guilds destined to face the Disbanded Guild all faced Firebomb defenses instead, then 6 Guilds would get lucky and 3 would not. Assuming of course those 6 guilds all had 27 members that could beat a Firebombs defense, I’d imagine that the 3 that didn’t wouldn’t score quite as high.
Just an unfortunate situation all around. I hate to see a guild disband.
I’d also hate to see a guild with 1 or 2 members left jamming up the GW bracket system, dropping 2 GW brackets at a time. Maybe it is for the best that they disbanded.
Edit: There were times in our GW crusade that we encountered 1 member dead guilds that sometimes had 2 defender options. It is possible that the other member left sometime prior to that guild becoming dead.
A more fair option would be to have any guild facing the now empty guild face the options that were locked in at reset of day 1 (or their most recent GW day, such as the final day of the previous GW). It may be that all 5 battles would be vs the same opponent. That happens in other brackets. It may also be vs 5 opponents with Firebomb defenses, just as long as that isn’t the default, go-to option.
