Several things need to be considered before granting officialdom, many of which cannot be determined in a shortened time frame.
For example, how does the faction fit within the community? Are they creating more trouble than they are worth? Do they respond positively to negative feedback if it's provided?
If there is already an official faction for that ID, how are they different? Will a second official faction create unnecessary conflicts as has been the case before?
Is this faction a flash in the pan, or a novelty concept, that will disappear as suddenly as it appears?
Does the faction, particularly the leader, demonstrate maturity and patience, or do they snipe at the Admins with sarcastic posts about silly commodities when things aren't happening as fast as they would like?
As you can see, there are many things the Staff needs to consider before granting officialdom. Allowing a few months to pass, beyond the request, enables us to determine which factions will be viable assets and which are not worth any attention at all.
