User blog comment:Drkdragonz66/Removing Blocking Powers from Rollbacks/@comment-1906486-20110809162419

While it's nice rollback can intervene with bans, as they might be around and not Admins. There can be leading to abuse, in the case of being upset with others or worse. Overall it's nice to have but usually you can poke an admin, to actually note the issue and they can ban them if needed.
