If you are going to go stamina, you would not want to use a destro or resto, as those are only effective on Magicka based builds. You would want to stick with a combination of 2H, DW, Bow, or 1H1S.

I have a Redguard Stamina Sorc w/ Werewolf. It is a powerful because it can achieve very high maximum Stamina and high Weapon Damage which results in high damage output. I use 2H, Bow, and DW, and switch between these setups based on the situation.

The Good:
1) If you choose a race like Redguard, Imperial, or Orc you can achieve a very high Stamina pool. Sorc has a skill "Bound Armaments" that grants 8% max Stam when toggled. This stacks additively with a Redguard 10% passive, and eventually Undaunted Mettle 6% passive, and lets you achieve the highest max stamina in the game. Then when going into Werewolf you can get another 30% in form, so you can get over 50k stam in WW form. It is powerful.

2) Stam Sorcs also have Crit Surge. This gives you Major Brutality (20% Weapon Damage), and heals you on Critical Hits. It is a good heal (in PVE) , and allows you to run DW and Bow if you choose, and still have access to Major Brutality. Many other stam builds are forced to run 2H for Rally in order to get Major Brutality. However, the heal from crit surge does seem weak in PVP, so you will have some trouble with heals until you unlock Vigor.

3) The ability Boundless Storm also gives you Major Expedition (30% movement Speed) for 7.5 seconds. 7.5 seconds is a long duration, and combined with Streak the build can be fun, and you will feel fast on the battlefield.

The Bad:
Stam builds as a whole are at a disadvantage with the Thieves Guild update. Stam Sorcs lack a could damage dealing Stamina ability and most end up relying on using wrecking blow. Stam Sorc ultimates are pretty lackluster, so you will most likely run Flawless Dawnbreaker for increased damage, but not have any really powerful ultimates to drop when compared to most magicka builds. Also, even though you feel fast, in PVP with gap closers it is not that difficult for players to stay on top of you.

Also, Werewolf is fun, but takes some practice. It is definitely not an "I Win" button, and usually in PVP you put a big target on your back when you transform.

Overall, it is a fun class to play, however, it is probably on the lower end of the power spectrum if competitive PVP is your goal.
