I'm not a fan of periodic resets in most MMORPGs. A large part of the appeal of this type of game is progression. The ability to advance and increase capacity - resets would have to be timed appropriately with the progression speed, and I don't think the window for that here would be palatable to most players. Some have spent literal years fine-tuning and improving on the character they play.
This isn't an ARPG where you can speed run to max in a couple days. I believe I heard that's how the DaoC shard is run, so perhaps that game is more suitable for those who want that type of gameplay in an MMO-type format. Which is a good thing! Different games for different people, competition is good for everyone, even when it comes to old-niche hobbies

I strongly believe introducing that kind of change would inherently make this game into something else entirely. It's not just that it would divide the player base, it would require expansive changes that would fundamentally alter what this game is, and on something that's been around as long as this game, would be SW:G NGE/CU level of risk.
