User blog comment:Jackninja5DipperGravityFalls/Achievements - Advantages and Disadvantages/@comment-5558012-20171209055019

The biggest disadvantage you didn't mention - achievements encourage editing where editing may not be needed. Many users, for example, may see a badge telling them to add pages to categories. They tend to do so in good faith but such edits are usually not needed and creates a weaker, more unorganized category system. Additionally, the line between good faith edits and cheating is a very blurry one.

To me, this disadvantage overcomes the advantages. I want users that want to improve a wiki in areas it needs improving in. I'd prefer to see the Appreciation feature return.
