I'm sorry if I missed a discussion about this facet of the AltMeta, so take this as a comment from someone who doesn't know the reasoning behind it.
I personally would like to be able to shoot for those who have made high scores, without thinking that I might be climbing as they fall because of factors outside of the gaming world. Why would your scores not stay up?
This is actually a facet of the AltMeta in it's current state and really isn't a result of the introduction of classes.
The short answer is that it's due to the different method used by the AltMeta to calculate total score verses the method used by the official metaverse. There are pros and cons behind each method but I think the current method used by the AltMeta is superior for a number of reasons. I do have a chapter listed above dedicated to the explanation of the
AltMeta Scoring Calculation. Instead of me simply repeating these explanations it would help if you read the manual. Don't worry, it's the last thing that I usually do as well.
Besides the reading the manual a concrete example is useful. Take a look at the current 2nd page of the
official metaverse. The player that's currently 11th (who actually only recently fell to 11th) is Killzone. Folks that have been around for awhile may remember him. An excellent player, however by no means so excellent that he still should be ranked 11th in the metaverse after not posting a game for close to nine months. On the same page the character in 17th is similar, submitted a total of three games over the course of 2 days in his entire career almost 9 months ago and is still ranked 17th. Where is the fairness in this.
Anyway, there's no aspect of the AltMeta that's cast in stone. Everything that's been done has been done in the interest of fairness. If some aspect of the AltMeta can be improved or is thought to not be as fair as we intended then the scoring method, or anything else, can be changed. But read the manual and listen to the reasoning behind the way it's done and then we can discuss it.
[edit]
Actually the AltMeta does have an All-Time Total Class where a characters total undepreciated scores are kept forever. In this case the above mentioned character currently in 17th is listed in 41st position. This is where such a character belongs, ranked according to his all time score but not cluttering up the current rankings nine months after posting his last game. Also 41st is far more appropriate to his performance since the only reason he's so high in the official metaverse is because he played a couple of reasonably high scoring games and the official metaverse severely penalizes your rank based on the total number of submitted games.
