Dark side is fully lulz status. Whatever you need to meet the power requirement is fine. I got it on the second try, and I only failed the first time because I just went ham on AOEs at the start and malak ended up absorbing most of the tanks.
Light side is brutally difficult. Once you get the strategy down it's not too terribly difficult to get it down to just Malak by himself, but after that there's a fair amount of prayer to RNGesus, hallowed be thy code, that determines whether or not you'll be able to kill him before he drains you to death.
Admittedly my mods were not amazing - I'm sure that if you're one of those lucky buttholes with piles of 20+ speed mods just lying around, it's not nearly as bad. For my part, I beat it with Mission & Z both dead, everyone else in the red, and Malak at 28 stacks of Rage (he goes supersaiyan at 30 stacks).
