I never said that they couldn't tone down the GRAPHICS of the PS3 version without limiting PC. What about content that needs to be the same between users, like the size of areas? Also, plenty of game content is server-side and has to be the same between PS3 and PC users if they want to share servers.

There is more to a game than just stuff like textures, which can be scaled down for the ancient hardware of the PS3.

Please educate yourself... if you knew anything about ARR, you would know that 'PS3 limitations' is already a thing.
