Hey! I was asked by quite a few people to make a video explaining Destro and also about some of the more fine points of playing. As such I put together this video today. It's not very high production quality or anything like that, but it should work for those who are interested in learning about Destro, one of the most fun warlock specs right now. Below (and the first 30 seconds of the video) is a table of contents with links to where I talk about specific things, in case you don't want to watch the whole thing. (I probably rambled a bit in some sections, but I was attempting to explain things as clearly as possible)
The first section (column in the ToC) I go over the abilities themselves (think for a brand new warlock learning Destro for the first time)
The second section I go over some slightly more advanced stuff (new-ish to somewhat experienced warlocks.) The what to avoid section has some common problems and easy (ish) solutions to those problems that you can expect to see while playing destro.
The last section I go into a bit more on like my personal starting rotation and some useful addons and UI settings, stuff like that.
As it is almost an hour long I do suggest you skip the first section if you're not a brand new warlock, and primarily view only the last section if you are already experienced with destro.
If you have any comments/concerns feel free to let me know. I mostly just threw this together after spending maybe 10mins putting together an outline and doing 1 or 2 takes for each clip.
