Because farming gives you the same amount, if not, more loot then you would in a strike or whatever. Why go through the trouble of constantly dying, leaving teammates, and bullet sponge bosses when you have an easier time getting 5 times the rewards farming the cave.
Don't deny it, YOU KNOW ITS TRUE!!!

I tried farming for about two hours once to see if it actually worked. I got one legendary engram but that was it. However, after a few hours of [i]fun[/i] (keyword [i]fun[/i]) gameplay in the Crucible I have almost a full set of legendary armor from spending Crucible Cash. Farming just doesn't seem worth it.
