Not everyone who invested in celestial gear did so because of the magic find.
I made my celestial gear as soon as it was possible for me to do so. I got it because I did the math and found that the increases from a straight celestial build (accessories/armor) were far greater than running just rabid. I didn’t lose too much condition damage because I kept my Superior Runes of the Undead but I did take a significant hit to my precision leaving me with only a 43% crit chance. gasp
For me the pros outweigh the cons and even with out magic find I don’t see me ditching the armor. I’m sure there are others out there who have celestial for the stats too who won’t be that affected by the loss of MF.
