Top 10 Lists was never a feature that actually helped people store information on the wiki, so I never understood why it existed.

I disapproved of Forum's deprecation, but I can understand it. On the vast majority of wikis, it was either not enabled, or used very infrequently.

I am deeply against Achievements being deprecated, although I can sympathize with the technical reasons behind it. For some of the wikis I'm on, the Achievements system has been a fabulous incentive to encourage people to edit, and to identify rising stars on the Wiki.
