Easiest way to clear p1 is to use a Teebo/Wiggs team, preferably with TFP for tenacity down, but less of an issue on the captain than on the Rancor. From there, everyone needs to pull about 200k total and you're clear (assuming a 50 man roster). Door phases are the easiest to do that, p4 is the hardest. Basically, for your first run, your biggest enemy is wasted damage, so make sure to communicate.
And until you have it down to a science, don't bother with a registration period. It is possible you will need the full time to get it cleared.
