Hey there Warlocks, for some background information, I'm in a casual guild (6/7 heroic EN right now, likely not pushing mythics anytime soon) but at the same time, I come from a hardcore raiding background and really like to be at the top of the charts or at least feel like I'm really contributing. I currently main a Hunter (MM, currently pulling about 290-300k dps ST) , who really enjoyed the feel of Beast Mastery and the Class Fantasy as a whole, but as we all know BM numerically is quite lower than MM, forcing me into a spec I didn't really enjoy. Warlock was my original main and a class I feel like I can enjoy a lot more as a whole. If I'm gonna be forced into cast times and lesser mobility, might as well be an actual caster!
I just recently hit 110 on my warlock this past weekend, so I don't have much artifact power really invested (up to my first golden dragon in Destro), but I really prefer the demo playstyle. My main question is this, while I know that there are fights that destro shines in, for heroic level raiding, is demo going to be competitive, or maybe even affliction? Destro is not a "bad playstyle" for me, but the other two specs just appeal to me more.
What spec would you recommend overall that could compete with my Hunter's dps, but not really fall flat on it's face for any major encounters?
