By now we should all really know that Thunderbolt is probably the most deadly STAB move because of the nature of this metagame to be full of bulky Waters. Raikou was just the only electric that doesn't suck.....
In fact, a strong STAB Fire Blast is not Moltres' most defining dangerous attribute, it is a strong STAB Air Slash. In that it has a destructive and safe early-game spamming move that other Fires can only dream of.
I agree with Lemmi, Flying has always been the strongest STAB. Staraptor, Crobat, Honchkrow, all suspects banned that pounded through teams with STAB Brave bird (Crobat, believe it or not, was a pretty big offensive threat despite only using BB). Swellow and Moltres are both the biggest powerhouses on their side of the attack spectrum. Flyings most important attribute imo is taking out bulky grass types, which as or even more common than bulky waters, as well as getting great neutral coverage with a 120 BP move. Electric is a great STAB, but doesnt have any standout users besides Raikou.
While I was agreeing with the "always has been" part of that post, in the current metagame Flying STAB is still great (Venusaur is still #1, remember?). Electric STAB also isnt good in the current metagame, because chances are it's coming from a mediocre pokemon, who is Dugtrio weak.But the question entails the current metagame. Flying type moves aren't as good as you state. Swellow is often spamming Facade as Brave bird is to costly on it's Health state. (Honestly, does Swellow just run Brave bird just to hit ghost types?)
Moltres Air slash is very useful, but only when used in conjunction with Fire blast. Moltres wouldn't even be a 1/10th as good if it's main STAB was Air slash.
Electric is the best STAB in the tier in my opinion, and are people forgetting Rotom? He's an excellent pokemon and utilizes his STAB T-bolts to the fullest.
QFT. This is pretty interesting. As Lemmiwinks said, it's true that Flying is quite a fearsome attacking typing in UU. But, as PK said, we have to focus on the current metagame, which lacks Crobat, Staraptor, and all the other Flying-types who got banned from UU. I don't think there's one type which will necessarily qualify as the "best" attacking type. If we go by resistances, it's obviously Dragon. However, the lack of a UU Pokemon to successfully utilize Dragon (read: not get STAB), apart from Altaria, who doesn't have the most stellar attacking stats, makes it obsolete in UU. In Ubers, though, it's an entirely different story. The "best" attacking type is highly dependent on the metagame.PK Gaming said:But the question entails the current metagame.
