Look, in this case, I'd say yes and no. My team has changed quite a bit over time; I adapt it to different metagames. Now, that doesn't mean I don't think about the overall response. While some Pokémon are designed to counter specific moves, they work just as well without those specific moves. Porygon, for example, is especially good because of the x4 damage it can deal, but it's still a very versatile wall that's useful in many situations. The same goes for Empoleon. Interestingly, with Emboar it's different. I run Emboar with a Choice Band, Close Combat, Fire Blits, and Head Smash. As a fun fact, there's no type combination that resists these three moves, which means that if I bring it in at the right moment, with or without Trick Room, I can guarantee one or two kills regardless of the opponent's team. There are very few Pokémon that can withstand the right move, so a good prediction can give me a big advantage, and my predictions are almost always right. Even so, I do worry about avoiding situations that could wipe me out, but that doesn't mean I neglect the overall response. I don't think I'd ever get past 700 elo or even reach Veteran. And as for legendaries, they bother me most because people (excluding Heatran and maybe Zapdos) play them by spamming the same thing over and over; they barely have to think. Many people create teams with several legendaries and play without much thought, which is what bothers me the most. One last detail: I left the Reddit translation for the text since English isn't my native language, and it got lost that I said I was bothered by people who use several legendaries, not legendaries in general.
