Shadowknight endgame DPS potential

[Noselacri]

Can shadowknights put out respectable DPS? I've heard conflicting reports, but some who sound like they know what they're talking about say that with the final pet spell and high-level haste on it, plus Clarity on you and all that shit, SK DPS is actually okay. Is this true? Does anyone have any data or experience with it? I realize it won't rival the top DPS classes, but how does it stand in comparison?
