I think it's a case of both really.

We definitely need more unavoidable raid damage and harder hitting boss autos to give us more purpose than babysitting prog groups through mistakes. There's a middle ground between going several minutes without unavoidable damage and having to spam GCD heals non-stop. Encounters just don't do enough damage.

However, at the same time, they have to acknowledge some downtime is inevitable in the long run. As our groups get better, we get better at heal planning, we get better gear and we map out mitigation, we end up needing to heal less. So we need a filler for that downtime too.

So basically, we need a bit more unavoidable damage to heal and more engaging dps.
