I don't think the "rage" was intended to be an auto-wipe, I think it was more of a "if you're not even close it will take forever to do this so give up now", but still allowed you to clear it if you were a little slow (25 min instead of 20 for example). The hour kill on peiste I referenced earlier was 2 aegis plds, so it definitely doesn't require ochain to hold through rage. A similarly long gnat kill (took a while to figure out more debuffs trips Emetic more often), was done with Aegis plds, and while it started trucking (Triple Attacks with 300+ crits if bad luck alligned), it wasn't uncureable with good PLDs and healers.
When presented with a time constraint, and a challenge that is difficult to reach in that time constraint, the community response is to zerg, perhaps they were trying to avoid that. I kinda liked that a couple well geared PLD's and a couple well geared healers can hold the fight together while you chip away at something as an option. I'd rather they have created more pops to reduce congestion, but they claimed the pops would be unequal if they did that..
