Uh no, the raw output and/or mana sustainability is lacking for more specs than you’d think.
Also, healing through interrupts and CCs is a skill expression. There are healers pushing high rating in shuffle, but differences can be seen between which spec (although the top ratings aren’t seeing a big difference, just a couple of hundred ratings between the highest rated healer overall and the highest rated underdog).
^ Wrote that for a different topic, but it’s a quick overview of how the healer specs are performing and their differences in popularity. And that’s only solo shuffle.
So the problem is the heavy burst gameplay designs, and the raw healing output not pushing out enough. For example, there have been people mentioning how they can’t even keep up with the raw damage output even while freecasting sometimes. Others who run out of mana after just a minute of gameplay.
This is not normal. It’s a very hostile environment towards healers. But interrupts and CC is something that has ALWAYS troubled the lower rated more than the higher rated, and as you can see healers are pushing it to the limits of what their output and mana can do, DESPITE the interrupts and CC.
So no, the CC and interrupts aren’t the problem for healers overall. It’s that only 1 healer is putting out proper healing, without losing all of their mana while doing it, and can survive being trained while doing so.
The rest are reliant on the importance of positioning, and sometimes DPSers need to peel for them.
But that’s not solved by dumbing down the gameplay to what it was like in Legion, with little CC available and interrupts not doing much because of sustained damage output not doing much before deep dampening, so it was all about the bursts, but the bursts weren’t tuned as heavy as they’ve been since SL and now made worse in DF.
So a summary of this topic:
The OP hasn’t played much PvP for years, and is more than likely out of touch with PvP gameplay overall. In other words, it’s a rusty OP wanting everything dumbed down to PvE-levels of gameplay once more.
Heavy sustained gameplay design overall while making it so bursts don’t matter as much, subsequently places more value in faking and positioning than now. It also vastly improves QoL for healers overall.
