I've never really played at a high level (just around 1800's to 1900's on my arms warrior at the end of cata) but I think I get the gist of playing that can enable me to get high ratings assuming I put enough work in. I know as a dps to make hard target switches when something like a spriest has his disperse down or a healer is out of place. I know how to push cd's so when I use my damage cd's they're helpless as well as the importance of positioning and communication.
But healing looks so intimidating! I know resto druids are decent this season and I originally planned on going boomy but I want to play a really strong spec going into next season.
What are big things that you guys have to do? How do I make the transition from a dps pvper and dps raider to a pvp healer?
Edit: Please don't critique my character, I got some minor conquest pieces for the ilvl upgrade to go into lfr initially but since then I've changed my mind but had to keep the gear. On top of that I'm not gemming/enchanting at all or correctly because most of this gear isn't permanent. Just looking to gather all my gear then correct it. (Red parry gem was given to me by my partner. Lol)
