Forum:Can't kill Crawmerax :P

To preface, I use a lvl. 61 Mordecai, have a great volcano, orion, and defiler. Shield is high corrosive 2000+ with 161 recharge rate, health at 1000.

I can't kill this asshole. I am to the point where I can take his minions out pretty easily, but the soloing tutorials I see on youtube and read about over here simply do not work. I'm on a PC, and there seems to be no "spot" where he either doesn't spit gobs of acid which immediately reduce my shield to zero and health to 30, or any spot where I am too far away from him to have him charge at me. I am always "in reach."

I get off of the elevator, he comes right at me. If I make it to the crevasse on the right side of the plateau I can hang out there for a bit and take shots at him (orion works well, but I can only see maybe one claw or his back critical sport at a time), but in short order he turns around and spits at me from which hiding under the little shelf there does no protect against. Often, the game kills me before my bleed-out meter runs out (is that normal, I could swear I had two more seconds to kill the __ worm).

As a corollary, is there anything that effects run/dash speed? It seems like my guy gets slower when I am fighting crawmerax; as invalid of a comparison as it is, I could run MUCH faster than mordecai, even holding three guns, a grenade mod, a shield, and a stupid bat-creature.

Thoughts?
