Got the wizard to 60 last night. I have to say I was a bit worried the fun would slow down... but it hasn't. I finally found two items with those cool attributes some people have mentioned. One with a 29% chance for a 300% weapon damage bleed over 5 seconds, another with a 30% chance for causing a mob to become a "lightning rod".. don't remember exactly the damage amount.
That along with two increased "Blizzard" damage items, a slight modification of my skill selection, and I really started kicking butt. I no longer needed to pull out the big skills for the elite trios. Just Blizzard and electrocute -- no problems. Got to Paragon 4 before heading to bed.
