Lean heavy into stamina and use 3/5 skills from 1 hand/weapon on your skill bar. Blazing Shield is a must (from your templar skills) imho as a solid 4th skill and try out "Inner Fire" as your fifth (from The Undaunted skill line) as a ranged aggro gen.
Just some advice to get you started. I put, something like, 43 points into Stamina and 15 into Health. Then I enchanted all of my gear (which is ALL heavy armor, great passives for tanks) for Stamina.
This has worked very well for me so far, but bear in mind I have not yet tanked in DSA, so I'm not sure if this holds up there. It has held up VERY well tanking in Vet instances.
