You're going to want to head to the timeless Isle, free 496 gear all day.....and you can get a "rare drop" 535 upgrade for a random 535 piece. As well as a free one in a chest. Grind some rep for a 496 trinket as well
Yeah I've been out there a lot on my paladin. The 496 gear seems to really only be 496 because the game says so -- it almost seems to me like it has a lower item budget than other 496 pieces. Honestly, if it wasn't for all the extra stam, I think most people would be better off throughput-wise with even the 483 LFR pieces once you take gem slots and bonuses into consideration.
My paladin is at a point now with his holy set where I won't need to do anything on the isle, except for maybe grind out the 535 trinket to replace the 483 Spirits of the Sun. For ret, I'll likely just be pvp'ing as holy and then buying ret pvp gear.
My newly transferred rogue has a bunch of the 496 pieces from the isle, but aside from the trinket, they don't seem very good. Just gonna have to get enough to get into the ToT LFR and not get kicked
