I’ve seen some terrible tanks in PF so wouldn’t say there are many more good tanks than healers, it’s just that healer death usually has a little more impact than a tank dying, although more often than not, when a tank does die, the run is over, because the OT doesn’t voke properly, or places the boss where it should be, etc, etc.

There are some really excellent tanks and some really excellent healers out there. I don’t think dumbing the role down will help
