Ok my RK tips.
DPS their isn't much to it, just keep on zapping. Make sure you throw up resist shield and do not fall to flame before entering fights though. Gives us that half a second extra to survive.
In coordinated burst damage target calling, RKs rock, we get to be the lucky ones that make those initial 2 big that drop the creeps down to half morale letting the hunter etc finish them off with thier high damage hits.
I the "Lulls" of a fight if there are any, throw up another do not fall to flame, giving your healers a helping hand. Great time to do it is when the TA is having a hard time finding a target they want.
Make sure you do not over extend. You know how short range heals are, don't make the healers job any harder than it is by chasing off after a target you should be focusing on.
FOR HEALING
Funnily enough a lot of healing is keeping yourself alive, which the rk can do in bursts. With combinations of glorious foreshadowing, bubbles, calming verses, do not fall to flame, resist shields you can stay alive for a long time and frustrate creeps to no end.
After you have frustrated said creeps now comes the challenging part. Keeping the rest of your raid alive.
1. Mending verses is your bread and butter, spam it on the creeps focused targets.
2. In those rare moments in fights where no one is copping a real beating, throw up a do not fall to flame/resist shield.
3. After this you can use a rousing words, usually after the first two though you have to start spending those carming verses on everyone.
4. Whatever our small bubble is, something of exaltation, is a lifesaver, literally. When the targets have a quick target switch, throw it at the new guy, gives everyone a chance to clearly see who is now getting targetted and throw some heals that way.
5. Essay of exaltation I use differently to most, if my entire group is looking a little low on morale from collateral damage, but someone in another group is getting focused. I will throw essay up then spam healing the focused target. Might seem like a waste but it gives you the oppurtunity to frustrate the TA again while not having to worry about your groups morale(temporarily)
6. I use our legendary group heal can't remember the name atm, in much the same way. I tend to save it more often for when I feel like my group needs a heal though.
7. Save calming verses for yourself, when the wargs decide you are going to die, this is what stops you from dieing. When your shield wall breaks, this is what stops you from melting.
8. Move with the group. A good leader will keep the targets called around the healers, do the leader a favor and push forward with your dps. You are the focal point of most fights, don't run away from your other healers, don't stand 40m away trying to survive against 3 wargs, move with the group be part of the fight.
9. Doesn't need to be said, but trait blue line, don't be cheap.
10. Don't be afraid of using epic of ages. It is such a good troll heal, creeps think they nearly have something down then boom full morale. Nothing gets creeps qq'ing about op rk healers more than a well timed epic of ages(well-timed being the key). Do not start to cast epic of ages when someone has only 4k morale to go, the cast has to start early, anticipate someone going down and bring them back to full.
11. Timing is the key, and practice makes perfect. Well placed use of cooldowns, good timing of epic of ages and switching targets quickly and watching the whole raid, not just people in your group.
12. Also identify who the normal first target is, and throw ME SOME HEALS! lol
That is everything I can think of atm. Whizzy time to step up and throw some things up for the hunters
(not putting you on the spot at all).
