I could be wrong, maybe I am... but I think the base ruleset of aradune is about the worst for making it through the 80+ game. Inability to box 3+ means that nobody could knock down a lot of the more tedious quest content on their own barring a few clutch duos. Even if YOU don't want to box 3+ it hurts that you can't get carried by someone else that does. On selo for example, where they did make it through all the expansions, a great deal of the nonraid requirements got carried by a few of the 6boxers who repeatedly grouped different people through or ran things for excess taskadds to make sure everyone was set. On aradune you have to break the rules to do that.
you know they offer free transfers from aradune to rizlona right? It's the perfect 2 server set up. We got to enjoy limited boxing during the expansions where it mattered, and then unlike phinny/coirnav/mangler, we can literally get rid of the box limit and truebox all together any time we want. I suspect as early as either during or after the 70's era you will see most if not all aradune guilds transfer to rizlona because by that point unlimited boxing doesn't even matter.
