Gee, I don't really know if much has changed. I hate to see numbers thrown around without solid formulas and stats to back them up, so I'll have pass on my opinion for now.
The only certain thing is the blaze is OP, though this is more of an issue than a delightful balancing factor if you ask me. The problem is that blaze can be used as a large area AoE attack and from where I'm standing it looks like that could mean as much as 60,000 crits or more with a well tuned mage.
There have been images with stats, such as can25ada's post.
