We are considering allowing lvl 1 relevels.
Last time it was done, it was an administrative nightmare for the DMs and the admins that had to sort through hundreds of requests. From what I heard - and keep in mind this happened in a time when I was absent from the server, and this all is word of mouth with no real substance, many of the requests were:
Opportunistic - from players that had no basis to get a level 1 relevel but still wanted one anyway.
Untrustworthy - from players that falsely - deliberately or not - reported their corrected lvl 1 ability scores that would result in illegal builds.
Messy - from players that only vaguely filled the forms of failed to adhere to a standardized form that was necessary to make the process as fast and painless as possible.
If we do lvl 1 relevels again, we would have to subject the DMs - which are mostly a narrative component of the team, with very little interest to play logician and internet police - to another bout of the same issues that they were dealt last time.
On that regard, I don't know if old requests would be honored. Most likely, no, as they would have to be re-reviewed anyway, since the game changed and so did the situation in which those requests were approved.
But that's just me guessing.
Much as we might be attached to our characters - and I'm guilty of playing a very old lizard - sometimes, and by design, you have to bite the bullet to carry on. Cast away your inventory, your languages, your levels, and start again, or live with the weight of knowing you are no longer optimal, or that the build that you originally intended is no longer viable, or even valid in the case of AA/Rangers.
