XIV's popularity has only been swelling further as time goes on, and I'd assume that means an influx of new players who generally don't initially grasp that healers in XIV ideally tend to spend more time using damaging abilities then actually healing.
It's kind of an outlier in that regard as healer DPS is typically a luxury in other MMOs if it's even viable at all.
The first thing I noticed when I picked up healer in XIV was that "Hey, I actually cause noticeable damage to things", so I immediately took to the mentality of mitigating damage by making things dead faster.
