Ran the raid and complete the raid are two different things. I didn't complete it no, but we were also short man and didn't have the right cc. It was just to get a flavor.
However when hearing what people did it makes sense - yeah that would work with a full diverse party the challenge can be overcome and was.
People call it "cheese" tactics but I don't see it that way. It sounds like you and and others want less damage combined with less healing for just some builds, but I am sure you will bring a full self healing character right. I mean that is what happened before motu that is exactly what would happen now. People will bring the best self healing and post BYOH in the lfm.
