I know, i hoped for that too. It was a pity, wasn't it?
I know that the physical and special seperated in individual moves sounds complex, but after a while, it gets easier to remember. Not to mention pokemon have improved from this, with now more ways to expand the metagame.
On the topic of the metagame, it isn't so much as what game freak has done, it's actually the inventive minds of people. The metagame has been changed by both us as the people and game freak as the company.
