I'm convinced that Pachirisu isn't close to the trash I previously assumed it was (at least in doubles), but it's still a Pachirisu. It has some great moves for a doubles support Pokemon, but in the end, you can't forget that it's a Pachirisu. It's definitely usable, but it's not anyfin great.
pachirisu's bulk isn't that bad, but it's still definitely bad. 60/70 is poor and 60/90 is decent, but not remotely impressive. People were definitely overhyping its bulk, most Pokemon can take hits like that if you invest in their defenses.
