I always use the balcony at Ionar now. Spread my guys out, go pull with an earthshield up, run like the clappers back to the doorway to the balcony and open up. I just heal through the dispersal.

I still move at Loken, but I'm not sure how useful it is because I still take a whole shed-load of damage. Like the OP, I strafe left/right using a single keybind for all toons.

HoL actually seemed almost impossible when I first tried it. I had a really tough time with both Ionar and Loken, but then I dived into heroics as soon as I hit 80 so that's to be expected I reckon!

Mind you, I thought the same about other heroics - Utgarde Pinnacle and Old Kingdom come immediately to mind - and now they're all easy-mode farming, mostly due to better tactics (often learned right here) than gear!

I really should have a go at Oculus one day. There are some good strategies posted on these forums.
