I fully support this idea. It would be good for the long term health of the game. We were just discussing this.
I had to divorce myself from my stats and I am now ok with it but I understand why people want to keep their stats. I moved around within our family of guilds when my help was needed.
A couple points. First, without the alliances that guilds form, this game would not be what it is. Players help grow and teach players, including from other guilds within fhe alliance/family. In many cases it extends outside of the alliance into other guild collectives.
Second, these community efforts take place outside of the game on other applications that can handle the complex nature of managing the player base. We use discord, as do many groups. The resources we provide on our server are not available anywhere in game or on the forum. We are not unique in what we provide.
Third, moving between guilds is allowed and there are systems in place to manage it. Players aren’t discouraged to move around except for keeping their stats.
