If western RPG's were like the FF series, then all you would need is a bowl of popcorn and to occassionally press a command. There would be no reason to play it as such, only watch it for the most part.
The FF series is popular, aye, but something to consider is that feelings towards JRPG's aren't good due to the lack of progress in terms of character, story and choice for the player.
If WRPG's were all like that, and some are, then they wouldn't appeal to everyone. The joy of Bioware's RPG's and RPG's like Oblivion, Morrowind and Fallout 3, is that instead of being lumped with a character you had little to no say in, you can at least have a say, even if their personality is still connected to their progression in the story, you can still have choice.
Some WRPG's - Fallout 3, Oblivion, Morrowind for example, Divinity 2 in part, even take away any personality as such and encourage the player to be the one who makes the personality of the character they play as, that the player is the one telling the story instead of the developers.
JRPG's don't do that, they just lump you with a character who's personality is the same as many other JRPG characters and to follow a story which restricts the player in a lot of things.
To ask Bioware to be like Square and other JRPG developers is frankly illogical, if you have problems with the freedom of creating your character, of freedom in a game, then perhaps Bioware's games and several other WRPG's aren't your thing and you should avoid them as best as possible.
