Thanks a lot for taking your time to reply to my query.
I did as you said and replaced Finery with Renewal and my health never dropped more than 15% without healing me back up almost instantly. This was the sole reason I had the Prophet rune on Akarat's rather than the Rally one, to make sure that I can have a 'get out of jail card' in times of need. But that's not necessary anymore!
Heaven's Fury and Condemn feel very powerful and it's very refreshing to be using other sources of damage other than Blessed Shields again and again. I prefer using the Condemn Unleashed rune for instant damage on the Rift bosses as Blessed Shield covers most of my AoE already.
I usually have my Templar full geared but I was trying out the Asheara's set bonus on my Barbarian today and transferred all the equipment to his followers, but now I got it back on. I then did some solo Rifts with your feedback on my skills and I even got my first Akkahn's set piece drop!
I would love to see your input on what you think that I can improve on, apart from getting the Akkhan set items which I can't seem to find.
I'm currently farming T2 rifts in groups and I feel like I have the damage and survability to do more, since I clear very easily with my Blessed Shield, yet as soon as I try T3, I get my ass kicked by the first elite group I encounter even though I have AR ~1000 and 19k Armor. Paragon points are put in +STR, +AS, +AR and Area Damage.
