Question about Mainhands. I am a Combat Rogue and have been using Trickster's Edge (ilvl 378, 551.8dps, 2.60 spd) and recently got a Blade of the Unmaker from LFR (ilvl 390, 617.1dps, 1.80 spd). I'm using an ilvl 378 1.4spd dagger in my offhand (Mandible of the Old Ones). So my question is, which mainhand should I use?
I've done a little testing and I'm getting mixed results. Training dummy says the lower level, slower MH does about 1.5k more dps. But it varies a little in LFD, but that could be due to varied buff strength with the random groups. I've always seen the rule of thumb for stat priority as MH DPS > everything else, but I'm not seeing that I'm getting much higher dps if at all from the higher damage (but faster) weapon.
