So the new renown schedule is better, but does it consider all? I would say no.
I think the schedule makes the assumption that any guild that has one account is merely on its way to a "better" guild with more accounts. I am in a solo guild, intentionally, and it hurts. Maybe they assume a solo guild doesn't want to be prestigious, but I think that is a little presumptive.
I don't think it's fair that two guilds, one of 1 and one of 6, get the same decay but the guild of six gets twice as much renown.
