Another way to address the low noble count is to re-think the character limits rules. That doesn't mean abolishing character limits, but perhaps the rules can be tweaked. For example:
- Rather than increasing +1 every 12 months, every 9 or 10 months instead.
- Offer a +1 to certain players on the condition that their character will be in a fledgling realm or island.
- Give out more medals
- Give a fam/honour/prestige boost to players who go to fledgling, or less desirable realms or islands.
These are just a few off the top of my head. I'm sure the BattleMaster Brain-Trust, i.e. the collective genius of all of us, could come up with more and better innovations.
