Couple of things actually you seem to have missed:
- No Battlehealer glyph anymore. It's gotten pretty much useless with 5.4. Use Final Wrath instead
- Execution Sentence is a rather bad T90 spell on the basis of raidutility. Might not be an issue for your raid yet, but you should get comfortable using/timing Holy Prism and Lights Hammer instead.
- Sacred Shield has gotten replaced by Eternal Flame with 5.4. You can still use Sacred Shield, but it got nerfed pretty strongly.
- My personal preference is not to take any socket bonuses. I only take them if they have a good amount of haste or a shitload of stamina (as in, 300 stamina for one socket or sth like that). Otherwise I use 320 Haste in all sockets.
- You're missing nitro boots on belt (and parachute on cloak)
- Colossus was a decent enchant when 5.0 was released. By now, it's pretty much useless. Go for Windsong instead.
- You have lots of gear with Avoidance on it. It's probably because you lack other items for that slow, but I'm going to say it anyway: Try to go for Haste in every slot.
- Try to push your legendary quest ASAP. Both the tank meta gem and the tank cloak are pretty strong.
