Maybe.
But what happens if the console gamers, due to their controllers not skills, aren't able to do high end raids as effectively as people with a keyboard and gaming mouse? Do they nerf the bosses on the console server? Do they redesign mechanics? Probably not. They will probably just design their raids, even their high end ones, to fit the console players first. This is not only because they would want some semblance of fairness (even if that meant lowering the skill cap) but also because if this becomes popular with console gamers, they would have more say than PC gamers just due to numbers.
