Dude you're not funny, you're just ridiculously annoying. And you're not helping Droidz by scaring away potential customers.
To OP:
There isn't a whole lot of Cata content. But everything in the Legion section (and a lot in the MoP and WoD section) should work (almost) flawlessly on Cata.
For fightclasses, you can just use the built in fightclass editor. It's easy to use and you don't need more than that. You can have a look at all the MoP fightclasses I posted (all done with the editor).
