i would not bother pugging HM crota today, its going to be endless scrubs who die in the first room every try. normal is easy enough that even shitty players don't matter much. i also am pretty sure they are going to hardcore nerf HM crota soon and up the crux drop rate, so may as well take a week or two vaca from it and see what happens - even with flawless play its still such a RNGFuckfest of sword bearer posn and bugs that its just not fun at all.
i suspect this week after patch is going to be crushing to pug players as a lot of people who have killed crota HM 2-3x this week will just not bother next week, i got 2 of the weapons from him (and they both kinda suck) so there really isn't anything interesting for me loot wise from him anymore other than crux, i'd rather play something else than spend 1-3 hours for a kill even with an awesome team.
i will be online though playing SR4 tonight so if you get a team i can help get a kill, there are a bunch of tiny things you can do to make it a lot easier like bubbling on skulls for boomer distraction, having everyone go back in at the SAME TIME so nobody dies to boomers, bubble at start for overshield help, etc. while any group can do it the group that is imo easiest is hunter SB, 2 defender titans, 2 warlocks (for 18 orbs at start), 1 more anything, and at least 3 gallahorns. oh, and everyone having a helm that infuses (regen health on orb pickup) is almost as helpful as 3 gallahorns.
