In one month there's not gonna be a lot of new stuff in the game to do, other than credo chores and stat leveling. Fun of killing noobs on the every corner will shrink to couple of ganks or few raids per week, and the gap between top players and other playerbase will be already huge enough to neglect a game breaking thing - letting inheritance of w16 characters, which will have credos taken and some of the stats inherited.
So yeah, snowballing old character from previous worlds mainly for credos but also good stat boost. It'd be fun for me to play as I absolutely hate doing credos every wipe, but also a risk to move character as there's no industry to get your stats back.
