My point being, that is YOUR experience. It's not mine, and it doesn't match the experience of others either. Therefore any claim that the healing experience in the game is objectively bad is clearly nonsense. There are people on both sides, and I'm sure SE are constantly monitoring the situation and analysing the data to see what needs changing, if anything. If they don't change anything, it's because more people are behaving in a way that shows they don't have issues with healers as they currently stand. I don't understand the argument that the devs aren't listening or are ignoring you deliberately; no, they are doing what the data indicates is the most player retentive/proftable. Anything else would be the height of stupidity.
I get that this annoys you. I understand why. But the solution is a change to the most demanding and complex content in the game, not to the healer kit. 90% of healers don't touch that content and don't want to, and that's where SE should focus a bigger demand on healer skill. Not by adding more complex DPS skills but by increasing the opportunity for mistakes that require more intensive healing/more random damage and so on
