Brusalk, please add a FAQ section to your guide, there are many warlocks that have similar queries that can be all solved through a FAQ.
Just by looking at the front page of the warlocks forums I found these questions:
1). 4set vs Offsets
2). Which talent/glyph to use on each fight
3). Difference between M>C>H and M>H>C
these are just from the first page, plenty more on other pages and on the pages of this thread.
