It's sad to see how bad our dps is. People at 70 were hitting numbers similar to your test. The bloodlust issue is something I have been trying to figure out. If you put 3 LB in between the Lava burst cooldown that works great. If you are bloodlust you may need a 4th LB or your Lava cooldown wont be ready. So far I have not come up with a good way to macro it.
