Dinged 85 on my shadow priests earlier this weekend. Levelled /transferred them to a new realm and got them a full crafted pvp suit + spire of scarlet pain (378 boe staff) ready for each.

Jumped straight into arena with a mate who has a resto shaman/ pally & druid. We tried out everything and not sure yet what works best for the team.

But ... 4x ...
fear on 23 second cd
4x disarm on 1,5m cd
4x dispersion on 1,25m cd
4x fade on 15s cd
4x mass dispel
4x vampiric embrace
4x ranged silence on 45s cd (better than strangulate)
4x leap of faith on 1.5m cd
4x fear ward on 2m cd
4x mana burn

Fear followed by Hymn of Hope and divine hymn is very strong, even if not for full duration and can be repeated.

I Basically opened with silence on healer, putting dots on 2 different targets. You see their health drop straight away.
Mind spike, mind spike, mind spike -> instant Mind Blast crit = this will kill anything.

On some occasions I experimented with mana burn on healer, but thus far it has not been really necessary.

Every game I think I saved my healers life twice with leap of faith. Simply amazing tool.

Took me 14 games to have my points for the week.

To me this feels like an improved version of a wrath shaman team.
