I've noticed something about smogon. If you look at pokemon movesets in past generations, each pokemon has at least 3 movesets or even more, even the shitty ones. Tyranitar has like 6 in DP.
In XY and SM, instead each pokemon has like 1 moveset, or 2 if it's lucky. They don't care anymore about experimenting with different stuff, unconventional strategies and stuff like that. They just keep using the same fucking movesets, and copypaste them on various pokemon, just because they have to.
This is really symbolic of how lifeless and sad pokemon battling has become. I advise you to battle in older generations if you want to have fun.
