Hate to say it but healer has just been another dps since ARR in dungeons, nothing has changed. I run dungeons with the same WHM all the time and they know the drill, only need to heal me if the dps is crap and trash pulls are taking too long and even then healing is extremely minimal and all of this is based on a dungeon done by some of the best people in the game, guarantee that over 80-90% of groups would not pull this off without a pocket healer around for emergency healing when shit goes tits up.

I agree healers need more but its not healing, they need more skills for dps because dps on healer is boring as hell with very few skills but people that are actually striking purely because you can't heal are not playing the job properly you are a crutch for when shit goes wrong when things are not going wrong you should be doing dps.

Most of the people here complaining are probably healer pures with some people mixed in that knows its other things that is wrong but healer pures that do not know they have dps buttons are a waste of space and I hope you play something else. Nothing really changes for 8 man content either, keep the tank alive and heal raid wides, outside of that dps, Only time you will be actually properly healing in 8 man content is with a group that does not know what they are doing. Don't mean to be rude but this is and has always been the case and it is best you realise it now and work with it or start thinking is this the role you want to play.

tldr.
Changes to healer dps - yes
Make changes so I can actually heal - go play something else please and stop complaining, you are a waste of a party slot.
