371 is far more than enough for Leviathan. A well coordinated team can knock it out in less than hour. Given that you haven’t done it, say two, maybe three hours at a stretch (I did the final encounter last night with an experienced group and that alone took us an hour and multiple tries—sometimes that just happens). If you make an FTB event, I’ll try and make myself available. Leviathan is still a great raid with some really neat and unique encounters. It’s well worth doing.

As for Escalation Protocol—we just did a 9 person DBO Escalation Protocol last weekend. The run I was in took all of thirty minutes, and it was ridiculous fun and absolute chaos. There was talk of trying to make it a weekly thing, so try and jump in if you see it happening. It’s honestly my easiest Triumph so far. (:

Just a quick note here. We took kidtsunami's dad through Leviathan earlier tonight. He'd never done it before, either. Took us about an 1 hour and 45 minutes. To be fair, we actually did extremely well, everyone was pretty much on point the entire time with very few minor screw ups. But even at double that, you're looking at three hours. We could definitely get you through a raid in an evening, if you're interested.
