Finally i want to change class.I want to become a Priest because i heard that they are the best healing class in WoW.
No, no we are not. As much as I love my class, I still run into Druids in arenas that just school me. In LFR I am super happy when I see we have a geared Holy Paladin who picked up healing the tank.
Because of Disc's healing style we can effectively preemptively snipe raid wide damage, and we look great on healing meters. This is not the same as being the best healing class. It does mean that we pair well with reactive style healers in a raid environment and that there are some bosses that we excel at.
Should i change from paladin to priest , druid or shaman ?
If you don’t like the healing style of your pally, or want to fill a different role in end game content, then switch. Your pally is in a good place, don’t let that be the deciding factor.
I LACK CONFIDENCE :/
In the end confidence comes with experience. It will take time to tell when you are doing a good job or when you really missed something. Did the DPS just died from stupid? You can’t heal stupid, but new healers tend to blame themselves anyway.
You will run into situations where the best answer for the party or raid is to let someone die. Knowing that line takes experience and the confidence that comes with it.
Have you read “things you don’t want to hear healing pugs”? Listening to some of the things that annoy healers, and problems that the healer can’t do anything about may help give you some perspective as you try to become a better healer.
Best of luck with your healer, whichever way you decide to go with it.
