The problem with UU is that it has so much offense but not enough defense for balance teams to back it up. Therefore if you don't go on the hyper offensive, you need to have fairly decent unmon checks on balance or bulky offense or you resort to stall. That's exactly why UU is its cancerous self it is right now. Mega Aerodactyl, Specs Primarina, Breloom, Azumarill, Scizor, Serperior, Marowak-A, and Mega Bro just to name a few mons. These are just the mons that stand out as soon as I look at the tier list. Like this is just too much for a tier to handle at this point. With amoonguss gone, we just lost a core switchin to Choiced Primarina, Breloom, Serp, and Azumarill. Gliscor can't defend a whole team by itself.
