Talk:Arcane Knowledge (Season 2012 Mastery)/@comment-4642730-20111130035145

I'm on the fence as to whether or not it is worth it to take this mastery now that it's 10%, even with casters. To get it, you have to spend 9 points: 4 points nets you a mere 4 AP, the next 4 gets you CDR, and the last point for 10% mpen. The only thing I would miss in this is the 4% CDR. Even so, I feel like the nine points could be used a bit more effectively elsewhere.
