Like I said, I only have 15/30 of the items for Balance of power, and I probably won't do a full clear every reset. Some casual friends are only now getting started on that quest (I know, shocking), and my other two 110 haven't even done the dungeon part yet.
With a fast patch cycle, this is moving from a current content goal to putting it on a low burner and waiting until I outgear it. My alts will probably do ToV LFR and Kara before they go for Balance of Power. This is chipping a little bit at the value of that content, don't you think?
And, while this in itself won't make me give stuff up, if they actually keep releasing major patches every 2 months, it will put serious pressure on my plans to get the prestige rank 9 weapon on 3 characters, since that is a long grind for me (I'm only rank 17 on two characters atm, haven't had the time to prestige a single time yet).
