>>50839822There is no such thing as "restricted" in OU. Legendaries are legendaries, and that status and their BSTs do not determine if they get banned or not. Mew was banned up through Generation 5 despite having the same BST as Dragonite, Tyranitar, Metagross, and Salamence, which remained unbanned, because of its utility. Those offensive Pokemon remained unbanned because they weren't deserving of a ban, but defensive and utility Pokemon with similar stats can get banned for being too defensive or bringing too much utility.
The main issue in why you don't see defensive Pokemon getting banned more often is that offensive powercreep is a very real thing, and defensive Pokemon are often required to check them. Several more Pokemon would need to be banned if Heatran, Zapdos, Ferro, Lando, Pex, Corv, and Clef were banned for being too defensive since defense necessarily checks offense. Defensive benchmarks are a very real thing, and they're what keep things like Kartana, Regieleki, Garchomp, Rillaboom, Urshifu, Volcarona, and Barraskewda from getting banned for being too offensive.
Game Freak has yet to make an obviously overpowered defensive parallel to, say, G-Darm. If they do (or when, more likely), it'll also get banned.
