U19 fixed wail, or so player tests have showed. My own experience with wail is also that U19 fixed it.

Based on your posts in this thread, you're a self-professed frustrated melee who is annoyed with wizards for marginalizing your contribution. That bias undercuts the credibility of your testimony regarding wizard effectiveness.
Personally, I tend to believe teh_troll. If low/mid-60s necro DC can be effective, then sounds like reasonable game balance to me. Low-60s is attainable.
