As the new feature seems to be still in idea phase maybe there is still some time to reconsider...
Balance is a fine concept - but as it is I believe MD is very much inbalanced towards geriatry already. There were quite a few major developments that were basically closing the door wide open so far: drachs, angiens, top crits levels.... Also, crits aging independent from character aging. They all create situation, where activity is secondary to the characted registration time. I understand one reason is to help MD build its own identity and myths, based on players that are active the longest.
You are right - resources changed the balance a bit, they may change economy more - we shall see. Still, no amount of resources gathered and currently available cauldron goods will buy a single drach old players have abundance of...
I am enthusiast of making crits more unique (like: registering their number of wins, transfer history - see new ideas section).... but I do not like the idea of rewarding just the fact that somebody recruiited them very long time ago.... It's further inbalancing the game towards age vs activity.
Unless the hinted development is a part of a major change rewarding activity too.
