Ah, insomnia at its best. 11:00 AM and still not asleep!
Do keep in mind when judging these that nothing was done in a vacuum. Other classes will be getting new talents too! I've tried to be pretty balanced with everything, but ultimately the concept is what matters, not the exact numbers. Also, do make sure to look at all the talents, some of the old ones were tweaked as well.
If you're at all interested in all the iterations the trees have taken you should check out my thread on the Blizzard forums. I started with a few ideas, added to them, tweaked them, took feedback from the Warlock community, and this is what we're with now. Do post in that thread to leave feedback and maybe we can see version 5. With enough positive feedback ...and keeping the thread bumped enough... maybe Kalgan himself might look at it and get an idea what kind of talents we'd like to see. (As an aside, after seeing the devs on the Blizzcon videos they seem like pretty likable dudes, which is kinda funny since they seem like such jerks in their forum posts :P)
