I'm wondering the same thing. I'm thinking of going melee just a little bit but mostly attacking from a distance. That way I can blow things up and if they get to me I can whack them over the head and take a couple of hits.

The only race to get both a Stamina and a Magicka bonus is Dunmer. That will boost your resource bar and damage (or healing) for both melee and magic. Argonian is a nice possibility since they'll heal themselves more.

Otherwise you could pick a race with better bonuses in one category and make up the difference when you pick your attributes. Honestly, I don't think race makes a huge difference in this case.

I'm playing a Templar as my main and I am a High Elf. I think that is the best race to play as if you plan on being a healer or caster Templar because the High Elf passives are awesome for magika management. I'm playing in light armor for both weapon sets. My primary is a healer (Restoring Light) using a resto stafff, and then I can swap to a destro staff and use Dawn's Wraith and get awesome burst damage. But of course all of that info is only if you plan on being a caster; I'm not really sure which race would be best if you wanted to swap between healing and melee dps, Breton perhaps?

I'm having an issue with my sun burst (I think that's what it's called) doing very little damage compared to my sword, though it may just be me and its the way its supposed to be.

I like dunmer, fairly balanced in magicka/stamina pools with a slight increase with magicka. Along with the extra fire resistance, giving you the potential of viably playing as a vampire. Allows for tons of versatility.

If you want caster/healer templar then Breton, only.All racial passives are about magicka regen except spell resistance, and also have +15% buff to light armor line experience. Best choice.
