I done a SOF run today as my trial roulette and we cut it close to 10 minutes left, but we still won because no one in the party raged at mistakes or wipes and we kept going until we cleared it. However, I do understand the frustrations that go on since the trial leaves little room for error and if the current won can't be salvaged, nothing can be done to make the dragon walk faster, which wastes time in a trial that already takes up quite a bit of time to begin with.
