The only consolation that the current design has (in casual content) is that good healers appreciate bad parties, because it actually gives them something to do. Any normal roulette, with geared and moderately-skilled players, will be easier than making mac and cheese. Because it's designed to have a near 100% success rate even for min-ilvl first-time players, like during the first week of an expansion. After the first week though, that turns into a near 100% chance of the healer being bored out of their mind... unless the party is trash. Then vuln stacks kick in and fix the damage tuning to be moderately threatening again.
I think this is less of a problem in other MMOs because you have more freedom to either run the casual content without a healer, or at least spec/gear your healer for more damage and less heals. In roulettes, you HAVE to bring a healer (or two), and they HAVE to have a healing focused kit.
I would love to solo heal some 8-man roulettes or queue for a no-healer Expert roulette as WAR. Or do some Bozja shenanigans that let me heal on Red Mage, or do a ton of damage on WHM with a couple extra damage actions.
But nah, the only choice for healers (in casual content) is being bored in under-tuned roulettes.
And yes, there's lots of other content to do like Extremes, Criterion, etc. And I do those as well. But EW relics require a ton of tomestones, and roulettes are still the best source of tomestones by far. And sometimes I just want to fight some junk, but I don't feel like rolling the dice on a PF group, ya know?
Rant over. Make more content with Lost Actions.
