Repeal the changes that are bad for the health of Codeforces

Repeal the division cutoff change Firstly, it causes rating inflation. In all div1 + div2 rounds the div2 players boost the div1 players, so even if someone does really badly relative to div1, he or she will get a much reduced loss, or even a positive rating change! In these div2 rounds there will be no reds/yellows to counter the buffer as well, so candidate masters will benefit even more!

Secondly, it does not solve the problem it seeks to address, rather it shifts it to higher rating ranges. Now instead of barely 1900s being unable to solve anything, we will have barely 2100 “masters” being unable to solve anything! We all know these titles are just for show, but this is a little ridiculous.

In addition, this shifting of the rating range also exaggerates existing problems. In rare occasions, even now, somebody will score 1st place in div2 and jump to master or high candidate master even if their skill level is low. With this change, we will have people jumping to grandmaster without even doing a single div1 contest!

With this change, ratings will become a joke. And that is why we need to repeal the division cutoff change.

Repeal the creation of division 3 There is no reason to have an “easier” contest for those under 1600. Problems A and B in div2 are typically easily solved by anyone, and the harder problems provide a challenge and something to aspire to.

Contests, whether div1 or div2, are already highly infrequent. For many players, even if there are available contests, they occur at inconvenient times. Obviously not everybody can be satisfied, so there is not too big of an issue under the current system. But this problem will become worse with division 3.

With division 3, now we will have div3 only contests! And a div3 contest that is being prepared by testers and setters and admins is time taken away from a possible div2 or div1 contest. Of course, this means that div2 contests will become even more infrequent. If you are in div1 -- you can forget about rating change.

So, we must also repeal the creation of division 3.
