So, what’s a “Warlocks for Dummies” course without Q&A time? Shayzani of the excellent 2fps (who has done the first couple of posts in her own Letters to a Young Warlock series, see here and here) and I will be taking your questions! Post your questions here (or on her blog, when she posts her question solicitation.) Gear selection questions? Talent questions? Specs for leveling? Whatever your warlock questions, post them, and Shazani and I will give our feedback.
EDITED TO ADD: You can also send me a question privately at feldeeds at gmail dot com. I should really figure out how to put in one of those contact-me pages.
