Let the blastpods take care of them, when they get down do not revive them then finish up. By the time they get back from extract you'll be done.

Yeah I've stopped reviving anybody except people I know for just that reason. The more people die the faster I can complete it
I just go to another crystal and hope the fools actually manage to kill the crystal in time... or just ignore mount tam altogether as this is where most of the red crystals spawn and half the arkfalls fail there anyway. Or just get 1 kill and leave as you still get exp, let them waste their time... i mean, i did that a few days ago, went and did 2 more side quests and 20 minutes later got my exp reward. Way too long.. only arkfalls I want to take forever are little ones as I can use them to get weapon skills (sieges have replaced that though).
