That first boss in ramps was much easier for me with the following strat:

Target the far healer --> lightning bolt
Target Gargolmar --> EM+CL
Target the other healer (only one left alive now) --> lightning bolt to kill him
5x downranked lesser healing wave on whoever has aggro
DPS Gargolmar normally with the occasional LHW on the aggro target.

He's stupidly hard at 59/60 due to crushing blows. Once you hit 61/62, he gets WAY easier.

And I'll post a vid of my Vazruden strat later. Holy shit was that the easiest fight ever.
