Not all jrpgs are like FF, calling JoJo generic also shows ignorant you really are. Also Kai Leng was not made to pander to jrpg fans as he was introduced in a book (his first apprentice was in fact good) what he turned into in that shitty book and ME3 is not what anyone wanted, let alone jrpg fans.
That exactly why he was in the game, and why he was doing ridiculous cartwheels. Even his boss fights were reminisicent of JRPG's. He just did cartwheels while you fought his minions. It felt almost turn based.
Drew Karpyshyn wrote gold, in games and books. I know Drew was awesome. That is how he was shown in the game though. Also he was bad in Deception, but that sure wasn't Drew Karpyshyn. : )
Also I am not calling that particular game generic. I am saying that Bioware already did a pretty poor job doing JRPG type stuff. That is not there thing. Also not everyone likes JRPG's. The only JRPG's I like are MGS and Dark Souls and the latter for just game play and you will probably argue they aren't JRPG's. You will find a lot of people with the same tastes.
I liked Bioware games BECAUSE they were not like JRPG's. Why would I want to see them copy them lol.
