Maxing out the value of the sha-touched weapon you have will improve your performance right now, which should be your goal rather than waiting and hoping for a weapon you may never get.
To put it in perspective, your net gain of having the mace with that OH over the staff is 104 intellect, but the haste/crit itemization of the staff will probably end up being better than the 733 spirit you get on the mh/oh combo which will further narrow the gap. Given current levels of intellect, that 104 int is going to translate into <1% dps on your overall performance. In summation, take the staff, let your healers have the mace.
