Discipline is the BG/Arena spec of choice.
The reason why you see a lot of shadow builds on here is because it is the leveling spec and that is when people have the most questions. Once those shadow levelers hit 70, many respec to holy to do raiding and that is why you see lots of holy builds.
As for a Disc build I'm not very up to speed on my PvP talents but I'd say the following are a must:
- Martyrdom
- Imp. Mana Burn
- Focused Will
- Pain Supression
Then probably hop over into Holy and get:
- Healing Focus
- Spell Warding
- Blessed Recovery
Just a few ideas, like I said I'm just picking what I'd take, I don't have any Disc experience in arena.
