It's been a while, Bladedancer here.
I haven't found anything that can quite tickle my fancy like Wurm does. However, despite itching to play again, I have been waiting for a couple of years now for a full game wipe, reset and merging of all servers. I have played on both clusters, extensively. Till this day I never understood why more servers are created without removing the existing ones.
I cannot imagine this happening though, due to the massive amount of effort, time and money spent on the development of some people's characters - I can imagine why these people would adamantly refuse a full wipe. I honestly don't blame them.
The game will ultimately stagnate slightly due to the split development process that Wurm has taken upon itself, it is terrible game design (Coming from a games programmer). To attract a new audience, bring back old players and reinvigorate Wurm, my suggestion is a full reset of the game and a re-release with new maps, on one cluster and with a clear and single path of development.
