Only theymos can know,  this why you ask him only . I see some adaptions suggest by members for improvements of merit. Further time required for for testing. Theymos like Bitcoin developers. Slow and gradual test not quick to change like alt coin developers, big timeframe for evaluate before further change. Some member want fast tweak they suggest, they think it will improve. Merit stop lot spams and bot used to grow high rank for sale . I think rank is over concern by members. Only Ivy tower you are prevented. Small rank can post everything and read same as legendary rank, so rank not important but can pay more for signature if you want to have when you are hero or legend but will take some years . Merit make some problems with dispute and argument. This will maybe fix next update. To conclude, no big change nothing I notice being talked about , tweak and improve to merit is possible reduce 50 to less amount .
