Ash doesn't need weak Pokemon either (Torkoal), so I don't see your point.
Point is can we have a generation where a non-Starter type and quadrupedal Pokemon is properly depicted as the regional ace (Krookodile was half-baked). I'm not saying Incineroar or Decidueye should suck, but give Lycanroc the main role.
I mean it's not like Torterra was all that impressive.
It would have been if not for Suicide Mountain.
