Tips for a noob at disc priest pvp?

Hey, I'm having a hard time 2s, mainly because of survival. I feel like I have no time for offensive play when they mostly go on me, I have 881 resi.

I'm maining a resto druid and it feels like I can take care of alot more pressure unless someone's spam purging.

As a priest I'm trying to keep my shield up alot, I miss my fears constantly but I havn't bothered going hit since I'm focusing on mp5 regen:
I'm also going oom fast as hell, unless my partner (UHDK) draws aggro.

Currently 50% of our matches and I'm feeling stuck at 1600-1700 rating.

get gear
use shadowfiend on cd when <70% mana or lower
tell dk to peel more using chains
focus on dispelling him and his target
position better


overall without gear you wont reach much
