I raid so I'm getting the weapon regardless of what anyone says. Secondary stats like det vs crit will even out in the long run so I don't really pay attention to those. Weapon damage gives stronger heals and every bit of healing is almost as valuable as every bit of dps. WHM will be required to burst dps in A3 as well so the extra weapon damage and crit might come in handy. If you don't raid, then I guess you just take whatever the prettier looking of the two: weapon or robe. Relic weapon might still be about 2 months away and by that time I might have the gordian cane already which renders the new relic weapon obsolete.
