On my 2 lvl 32 Titans I didn't "cheese". Just played as if it was a ROC strike: bubble with weapons of light and rockets/Black Hammer. Switched to a void fusion rifle for those damn Psions or used void grenades. Just did it today with my lvl 31 Warlock and got under the ramp and sniped. My warlock is only a month or so old so I'm not as comfortable with the jumps/glides/etc. Id rather play it safe and get it over with. I like the ROC version of this strike, it's really easy. But this Nightfall version blows. It's not hard, just tedious.
