Unfortunately Templar tanks don't have a reliable healing ability that scales off max health like the other classes. I tried playing a Templar tank like a DK tank half a year ago and disliked the fact that it needed a healer for survival. You can generally use Extended Ritual, Sun Shield, and Breath of Life for survival.

For sets, I'd recommend a typical tank set-up: Ebon, Alkosh (or Torug's Pact), and Lord Warden (or Earthgore/Thurvokun). Front bar S&B and Ice Staff on the back bar. Front Abilities: Honor the Dead (or Meditate - Psijic ability), Heroic Slash, Radiant Ward, Pierce Armor, Restoring Focus, Ulti: Refreshing Barrier. Back abilities: Extended Ritual (or Blood Altar), Repentance, Ice Blockade, Silver Leash, Inner Rage, Ulti: Aggressive Warhorn.

5-1-1 set up for max stats. Reinforced on chest piece, infused on legs and hat; rest sturdy. Enchantments are up to you, but a mix of health and prismatic defence (until you reach the stats you want). It might be interesting to run Battalion Defender instead of Alkosh in dungeons if you want extra survivability. Mundus either Lord or Atronach.

Templar tanks don't work the same as DK, so you'll end up similar to that Alcast build one way or another. Sun Shield is just too good to pass up as a templar tank and your heals will never be that strong. You could slot rememberance as your ult of course, but that's a "selfish" ult and usually your group needs warhorn or maybe Nova to reduce damage. Rememberance also prevents you from running around, blocking mechanics and reapplying taunt.

Your best bet might be a frost staff templar tank that could get a big enough magicka pool to make your heals stronger.

I run a magicka templar tank, so I don't have any problem healing and I rarely run out of stamina. I run with three tank sets:

Light tank
Burning spell weave 4 light 1 jewellery
Plague doctor 1 heavy 2 jewellery, sword and shield, fire staff
Mighty chudan

Medium tank
Mighty Chudan
Plague doctor as above
Dragon akaviri the rest

Heavy tank
Mighty Chudan
Plague doctor s+b *2
Vvardenful heavy set (warrior poet?)

Light set is for normal dungeons and easier vet dungeons. Medium is for vet dungeons. Heavy for hard dungeons

I do about 6 to 8k dps in the light set against bosses, whilst taunting the bosses and harder enemies.

Others here won't like it, but I find it works really well. I do the job of a tank whilst adding some dps when in light gear.

Dark flare, reflective light, Jesus beam, destructive touch and pulsar are my main skills. And taunt obviously.

It really depends on what you want to tank. If you just want to be a solid tank for pledges, and your group isn't overly concerned with meta, then templar tank is fine.

Most groups will want Ebon/Alkosh/Lord Warden b/c it's the go-to meta stuff. But if your group isn't as concerned, you could run sets that make up for what Templar lacks for tanking which is Crowd Control and Self-Healing. So you could use Swarm Mother for pulling mobs in, or run extra stam for being able to make high use of Silver Leash and even Bombard from Bow line for a CC. You could drop Alkosh for something that helps give you more healing like Bahraha's Curse or Battalion Defender if needed - though if you aren't doing super hard stuff you may not notice the lack of self healing vs. a DK/Sorc/Warden tank. I usually only notice how bad my self healing is when I do end game hard mode vet trials or newest dungeons. Breath of Life/Honor the Dead will do you ok for a quick burst heal (esp in a smaller group where more players mean more people to get the heal) for a lot of content, so it could work fine for you.

In the end, it will really depends on what sort of content you will be running and with what type of group you are with. You'll end up getting feedback and opinions as is stands for every level of gameplay when most of them might not even matter to you.

My dk tank has lots of set like ebon , plague , akaviri , galenwe , eternal , greenpact , warden and bloodspawn problem is the skills , Ive played warden tanks very simmilar to dks but templar I've no clue ¯\_(ツ)_/¯

I have 10 points in health and the rest in magicka. Will food and plague doctor, my health runs from 30k to 46k depending on which tank gear I wear I have between 22k and 30k magicka depending on the set. I have no problem healing whatsoever.

I assume you guys are talking about stamina builds, but you really don't need much stamina to tank. It really is a myth.

The main problem with templar tanks is that most of their utility and group support is provided by the healer or dps.

If you are looking for a tank that can run dungeons with 3 dps and keep everyone alive, I would say templars are better tanks than DKs if you build them right. Templars just aren't made to be the current meta endgame tank.
