Sky,

While I cannot give you the answer you are looking for, I can give some general advice. There are 'natural' race and class combinations for certain roles. While it is true that any race can be and class can do any role, some are more natural fits than others. For example:

* Ranged DPS - Breton Sorcerer with Destruction Staff
* Melee Rogue - Khajit Nightblade with Dual Daggers
* Healer - Breton Templar with Restoration Staff
* Tank - Redguard Dragonknight with 1H and Shield

All builds should have a secondary Ranged / Melee weapon to complement their core weapon, if needed.

So, bottom line is this. If you are going to build a Templar Tank, you can certainly do that. BUT, it is going to be more challenging, and frustrating, than going the more natural route.

You may find it easier to do a Templar Healer or Sorcerer Destruction Staff until you learn how ESO fundamentally works (I prefer Templar as it has Ranged, Melee, and Heals). Then, when you are confident on the game mechanics, do your favored Race/Class/Build. Otherwise, you may quit in disgust when things just won't work as you would expect them to.

Good Luck!
