I completely disagree about using SoC. Using it in arena at low to even medium gear levels is a mistake. You are going for burst damage, splash is irrelevant most times. Look at the judgement damage between the 2 spells, one crits in the 2.5k range and the other nearly 5k range. multiply that by 4 and you'll find that you will actually burst down targets significantly easier with righousness. SoC is great for bg's because people don't heal that much and there are swarms but arena's they will just step away and cc you or get healed. I'm not pro by any means and i've only just started focusing on arena's but i did manage to break 1400 last week with all 219 weaps (except one 232). If a healer is actively healing your target your not really going to be able to take them down before you lose a guy. Your not going to make them have to chose who to heal and then kill the other.
I'd also suggest not wearing any pve gear for arena's, the difference between a few pve pieces and all pvp is very noticable in my opinion.
Always be rotating divine sacrifice with bubbles, even in bg's if there's more than about 2 opponents. It's 50% damage reduction for 6 seconds and 30% for the next 4 so it's HUGE. I've found it's insanely more effective to pop that first rather than wings on all. They also go for my dk like 90%+ of the time so I keep him in frost. Dk damage is terrible compared to the pallies imo so the difference between frost and any other stance is marginal. Having him survive so your pallies aren't kited to death is big.
I hope some of your guys are blood elf, the aoe silence is awesome. It even stops ret pallies from using skills for 2 seconds so it's great for more than just typical casters. Open up on a priest with aoe silence then stun just under 2 seconds later and you'll get that kill before they can blow the aoe fear.
I personally geared up pve first but regretted spending the marks on it rather than on furious. I geared up more in bg's and weekly 10 arena matches so the resilience makes a difference.
Do daily bg's every day (you'll need the honor, trust me), do all wg quests every week (used to be able to do them 2 times a week,tuesday then like sat or later but doesn't seem to work any more), do one daily random heroic, you want to get that 264 trinket for the pallies, it's a lot of extra dps over that terrrible arena trinket. I never did Voa but if you have time to run each of your guys through go for it. It's just really tough to get in one with crappy gear and no achievement and when you factor in random fail and loot not being for your class I just didn't think it was worth it.
Hilts are coming down in price, i bought one yesterday for 5.5k which is like 5 hours of daily's for me and well worth it if you can find em cheap.
just my 2 cents, take what you want from it! I love playing the dk/pally team. It's so much more fun than shammy team in my opinion. Not having to cast and be facing the right direction after blinds/fears/death coil's etc and not having to be constantly raped by whirlwind and other melee is a nice breath of fresh air.
