It's you that don't understand, my little level 50 BRD friend.
Here, an example for you:
Let's give positionals to all your heals. If you get them right, you'll heal normally. If you don't do your positionals, you'll heal as if you were in cleric stance. If you're healing at melee range, we will give you a bonus. Now, go have fun with a play style that you never asked for.
Oh, and let's make the brand new healer job the same, so there's no variety at all.
