....What game are you playing??? The only place that I have actually had to deal with bullet sponge enemies is in 980 NF and 980 nightmare hunts, and then that's kind of the point, especially since I'm 969 trying to do those. And as far as bosses go, again that's the whole point. No raid boss should be dropped after the fireteam shoots a clip into them. As far as everything else goes no other boss is hard to kill. I mean most other things, including strikes and heroic world events can and regularly are solo killed with ease. It just takes a realistic power level, at least a half way decent character build, and half a brain.
