Ok. Here is the funny part. Aside few, and by that I mean counted on the fingers of one hand, I consider most Jrpgs grindfests with flowcharts and stories written by people on drugs.
And yet I sometimes relish the idea of a grindfest every now and again. As long as it hasn't multiple kinds of grinding (eg weapons, skills, techniques, etc.) or difficult yet neccesary grinding (hello there Phantasy Star II)
As for western rpgs, while flowcharts still exist and combat is usually little more than clickfests, the story though is usually much better. Assuming it doesn't try to ape the bloody typical Tolkienesque mythology with disastrously laughable results yet again.
So, in my humble opinion, both western and eastern rpgs are flawed genres and in need of improvement. Mass Effect did provide an interesting, yet failed, attempt at improving combat and wasn't too complex. Now if the second one succeds at making the combat actually work great, then we could be looking at a great sequel.
And if both genres stopped using the "save the world from the evil wizard" plot point retardation, things could be better. Then again, the RPGs aren't the only genre to do that. A lot of films and games do that too. "Sigh"
