There's nothing wrong with Gym Leaders having Pokemon that counter their main type's weaknesses. Why does this make people seethe so much?
>"NOOOOOO THE ELECTRIC TYPE GYM SHOULD ONLY USE ELECTRIC TYPES SO I CAN GET A FREE WIN WITH GROUND TYPE POKEMON"
>"YOU CAN'T JUST TEACH AN ELECTRIC TYPE POKEMON A MOVE THAT COUNTERS GROUND TYPES, THAT'S CHEATING"
>"STOP FORCING ME TO USE MY BRAIN, JUST LET ME WIN"
It's sad that only the older games offered an actual challenge. Nowadays the new games lowered the difficulty so much that even a moron can't lose.
