>>50221622Electric is balanced because of how easy it is to shut them down with ground types that they can't threaten ever since hidden power was removed.
Normal should be in underpowered because offensively not being supe effective on anything while being resisted by 3 types is bad and defensively you will always prefer to have many resistance even it comes at the cost of many weakness than few resistances and few weaknesses due to team synergies.
Grass is pretty underpowered because of how many types resist it and hit it hard. Also, Spore (the only reason you would ever play a grass type) is only on like 4 fully evolved grass mons
Poison is a mixed bag, offensively it's pure shit but it's one of the best defensive types in the game.
Also there should be a tier between OP and balanced where Dark and flying should be and a tier between balanced and underpowered where psychic and poison should be.
7/10 good chart.
