So? Anyone can do EX primals if they have some time of their hands. Casual doesn't always equate to "easy". I'm pretty "casual" myself, but I gave Bis EX a few tries at the very least. And as Ezra said, the one true strategy for end game content will always be copied down by everyone else when the world firsts show how it's done. Scream "i'll play how I want to" all you want, but don't complain when your "me first" attitude gets you kicked from several parties because you didn't conform to the implied standard. There's an imposed standard for this game and every other co-op game with multiple builds/trees/etc because it's the most effective and/or is the fastest. People will not settle for anything less than that.
