Offense is not the only way to go man. Balanced sand is alive and strong, very strong, and Hippowdon is a champ in such teams. Hippo + Jellicent + Forretress + Stout is a tried and effective combo, which works perfectly. And also you ignore one major selling point of Hippo, he is the only weather inducer with reliable recovery, and as such, he is the most adept at winning weather wars.
And about Sect. As the time passes, more people will realize how awesome, and how easy he is to fit in a team. Don't forget we have been in this new meta for only 3 months. This is how he is going to reach #1.
