Focus target? PS3 users can do this very simple trick. Focus down the one being hit. To find it, you have to use your eyes, once found you can begin focusing it. If two or more mobs are clearly on top of it, your focus target will always be the one with its health going down rapidly. Starting a forum thread about not having a button and how it's ruining this game is absolutely ridiculous. Buy the game for the PC if you want all the "options."
