Clan leveling and perk system ought to be very interesting...
and it could significantly impact clan composition depending on how leveling works. If it is an XP-based system, it will be interesting to find out whether XP scales with clan size or remains fixed. If XP per level scales with clan size, then small active clans will have a huge advantage over larger more casual clans. If the other way around, some of the more casual players could easily be facing some heat over activity levels and whatever performance measures are used to earn XP.
