How close are you to getting your legendary meta gem?
Don't use glyph of riptide
I would put the haste enchant on your gloves as your mastery wont be as good due to a Holy Pali's absorbs.
At your ilvl you could trying going for the 5676 hbp for the extra tick of Riptide or even the 7613 hbp for the extra tick of Healing Rain.
If you are going to try one of these then I would gem + haste + spirit in your yellow sockets or even straight haste.
I'm pretty pap when it come to reading logs indepth, but make sure you are using unleashed life with every healing rain. Also your healing stream totem should be your top healing spell along with Healing Rain on Jin'rokh(N). Make sure Earth Shield is always up on the tank.
