If you're fighting pvp geared people and global them, they're not worth mentioning as serious opponents. Lets leave it at, you're setup is very good for the opponents you're facing.
And what exactly is unbalanced about 85? Most matches last longer than an average 90 match despite the burst some classes have (read, mage). There's nothing unbalanced at 85 that you can't gear/spec against. The only unbalance you might encounter is playing a double dps comp in full mop gear (lol) and 1shotting undergeared "twinks" at 1.6k mmr.
You realize you're talking from the perspective as a healer + hybrid comp right? Of course you're going to gem discusting defense, because you have offhealing and massive defensive capabilities, whereas all they have is burst. You have 200k hp on your paladin and 65% resilience. I have the same (if not more) resilience and around 1.5k more spellpower. if you come up against a dk + x melee cleave, you're dying. Popping all your cooldowns just means you end up losing slower, because there isn't much that can counter 60k AP necrotics.
Don't try and talk about your playstyle as if it's the only one there is. Because there are plenty. Double dps with the right classes with next to no resilience besides a pvp trinket will zerg practically any comp just because of how bursty the game is in general, bracket-regardless.
Oh, and just because you have around 2.1kish rating doesn't mean you own the bracket because your bg says #1 . It's not even close to that, and you should know it by now.
