Last Ditch Triumphs Attempt

Right, doubt this'll get much attention seeing as there's hundreds of this kind of post going on, but I've spent the last week trying to knock off the remaining triumphs I'm missing. I need KF Hard, the three calcifieds from challenge mode, and 2 random ones just in the raid itself. I am part of a 2-man since beta team that has 2-manned all pve content except for the raids and Skolas. Yes, that includes arc burn taken Saber nightfall, Sunless Cell exotic final step, all that horror. I simply have not had the patience to deal with wipe quiting randoms, and do not have the luck of having enough friends to actually man a raid pre-grouped. I have a HM Oryx checkpoint, and about 2 and a half hours before I get on for the final time before the big drop. That's 3pm Mountain, 5pm Eastern. Any experienced groups willing to take this poor bugger through challenge hard Oryx, then challenge regular Priest and Golg? Edit: Idiot that I am, I forgot what I play as. Defender Titan, 319~ light, happily runs mid bubble.
