Maybe it's just a Primal datacenter thing and/or unlucky weekend. On Chaos I see more clears than abandons on this trial. Rate of maybe 15% of groups that cannot pass it, although it's quite common to not one-shot if there's a bunch of first-timers. Once people have seen what happens and don't die to aoes then the dps check is usually met. I think these kind of trials get the echo added to wipes after they've been in the game a while so it will be indirectly nerfed and also as it gets older you're more likely to be partied with roulette people synced down to the maximum gear level who have experience.
