Where do you plan on running? If you are going to do strictly meph and pindle, blizz works the best, if you want to be a little more versatile, to run pits and andy and even D, make a meteorb, your killing speed will be a little slower, but you can run anywhere Blizz is easy, max cold mastery and all the synergies. A good meterob setup is as follows:
6-9 Cold Mastery
15-20 Fire Mastery (20 if you have little +skills)
0-5 Firebolt (5 if u have lots of +skils)
Energy shield if you so desire (just use an orb with it when u wanna cast it)
Actually, blizz isn't that good for pindle, he's cold immune like half the runs you go to. and i think rhyme is better for mfing, splendor has no resists, plus the cannot be frozen is a great mod too. But if you got a good merc, then blizz will go ok with pindle.
