Do you defeat the encounter before it enrages? The group had an acceptable performance.
I see no point in pestering a healer that only heals in a dungeon. Yeah sure it'll take a few minutes longer, big whoop. I'll take a "heal only" green over a "Imma try to play like a pro and let you die/wipe 5x". Same applies to a tank. Give me a tank that pulls single groups over one I cannot keep alive every day of the week.
Some people feel confident playing at a high level, some don't. I don't like people trying to pull of things they cannot do (gaining experience in new content aside, at some time a tank/healer HAS to check out where the limits are), if content gets cleared either way.
From my experience parsing myself: FF-XIV raiders are every bit as hardcore as WoW raiders. The differences are a bit smaller in number but I get the same head scratch moments of "how the **** do these guys pull off these numbers?!" when looking at the top.
