I think that if you're removing the points from the Logic missions, you also retroactively remove the points from all those people who have done them.
People like me who got a "late start" will NEVER be able to attain the same rankings as the people who completed all the Logic missions before the points were removed. It makes us feel punished that we didn't get here sooner.
Part of the draw to this for me is doing the challenges, bettering myself, and learning along the way. The other part is seeing how I "stack up" against others, and trying to attain the highest ranks. I will never be able to attain the highest ranks as there are people there who have significant advantage over me because they got their points while there were still points there.
Please don't take this the wrong way. I don't want to "punish" anyone.. whether that be the people who were first, or the people who "cheated" and just got "free points". I think the only way to make it fair for everyone is just to set the playing field level and either keep the point value, or remove it from the challenges and scores.
