Just an idea:
We have a ranking system for a reason, why not use that for the extra 3% instead of Fealty Rank? That way people would stop complaining about how capping is pointless, and people would actually have incentive to rank up.
For example:
I'd like to set the 3% XP Boost Avatar access for Lieutenants.
I'd like to set the 4% boost for Captains
5% boost for Generals
and 6% boost for Admins
It would work out sooo well if you could just let Leaders choose what is best for their clan. With the new Citadel totals being reduced to almost nothing, there is even less point to capping and ranking up in the clan. I'd really like to encourage my members to do so by attending events that take quite a long time to plan and set up.
