>>56281849>gave several new roles as mixed attackersThe physical/special split effectively killed mixed attackers.
Back in the day, if you wanted to deal with something like Skarmory or Milotic, your ONLY option was special moves. No Flare Blitz or Wild Charge to muscle through that. Similarly, something like Snorlax or Ludicolo could only be handled by physical moves, no Focus Blast or Sludge Bomb to get through it.
There's a ton of reasons to like the physical/special split, just try next time to not pick one of the things that objectively proves you have no idea what you are talking about.
