Want to try and do some runs, but considering the stat squish coming in endwalker I dont know if if this "game" is going to be a thing or if it will be listed as a new game on speedrun.com?

I could be wrong, but I think they'll just change the name to match the new xpac.

I'm just wondering if the Stat Squish will affect current runs and rules. Will everything stand, or are we starting fresh?

For now everything will remain the same, until we get more info on the matter nothing will change.
