Out of idle curiosity, i decided to see if the Spellpower changes had made Horrid Wilting any better for my Pale Master. They did not.
This level 8 spell, the highest level damaging Necromancy/negative energy spell, does between 400-450 for me. Meanwhile, I'm getting critical aura ticks for around 200, and my Necrotic Ray is often in the 1-2k range. As an AoE, it is far outclassed both together and individually by Lesser Death Aura and Death Aura, level 2 & 4 spells. For nuking DPS, it's worse than a level 6 spell (that also has a shorter cooldown).
This spell could use a change. More damage, a secondary effect, shorter cooldown... these are just some of the ways this spell could be improved. Please give a necromancer a reason to slot their highest level damaging spell instead of, say, Greater Shout.
