While I don't claim to be a great warrior, I've had decent success on Horridon lately.

My strategy is to bladestorm + bloodbath when the first group of 2 wastewalkers comes up, then save it until the 3rd door, where I bladestorm when the two warlords come out. Get as many mobs involved with the bladestorm as you can obviously, I guess it could be considered "meter padding" but I've found it to be pretty effective, especially since I didn't get any real gear upgrades until this week's Tortos kill. I can type out my full Horridon strat if need be.
