While it won't fix all things, it's definitely a start, and a good one: Mind Flay's coefficient will be raised by roughly 30% "to start," and it will gain the ability to crit. Yes, that's right. The coefficient will be de-gutted, and it will benefit from crit. After months of nothing, this is like a ray of sunshine from the heavens. Koraa also mentions that they'll be looking at the rest of the Shadow tree, but states that most people agree the tree itself is fine, the issue is the Shadow spells themselves, which I will more or less agree with. While some new spells would be nice, the class is plenty functional with what they have assuming the numbers will be tuned properly, and our gear matches up with that.
Hopefully we'll be seeing the new and improved Mind Flay in the next beta build, but it may take a little longer than that since it will be a complete rebuild of the spell. As soon as it's in, I'll be back here raving about it, I promise.
