From some other locks on server with full t6, the build I linked was in the 2700-3100 dps range in sunwell.

That would be my build for 70.

I feel that mages were pretty hard hit in showing (although I expected that) but I was honestly surprised by how, to be blunt, poorly our warlocks did in raid. I can say with certainty that ALL our hamfist warlocks are exceptional players, and have always had a very solid showing on the meters. Blizzard just was really not very kind to you guys at all on this latest patch.

I'm not sure if these things will help you guys, but I noticed a few things that were affecting my own dps that was probably caster generic. First, my crowd control macros (although there isn't much to banish in sunwell) were NOT working to do my standard "left click CC's current target, right click CC's focus", which was slowing me down because I had to manually change targets back and forth and I'm usually a LOT faster.

Next, there was something going on with spell animations for timed casts and not being able to tell the difference between a spell that truly got interrupted and a spell that was going to go off. This happened when I would hit a spell key bind more than once. The animation (on my hands) would disappear, the cast bar would stop/disappear (I use quartz), and then I would have to wait a few seconds to see if the spell was really going to go off or if I had actually interrupted it and needed to cast it again.

Lastly, the stock UI floating Combat Text is not helpful for a ranged caster for a few reasons, so I found myself going back to a buggy version of SCT & SCTD. The stock combat text shows above a target, and when you're ranged it's hard to see those numbers tick if you're far away and the target is particularly large. And in order to see stuff in a dynamic fight, you have to keep screwing around with your camera angle which is super annoying. The stock combat text was also not showing my procs, such as Hot Streak, which is a talent crucial to a fire mage's new spell rotation.

On the PTR I hadn't had too much trouble figuring out when Hot Streak (instant cast Pyroblast) proc'd, because it was always the last graphic that appeared on my buffs below my portrait. One of the new changes I noticed was that buffs are being arranged differently; your own personal buffs are always listed first, and then any raid-wide type buffs follow. So, in a sea of 20+ buffs on my character, all of a sudden instead of just having to look at the last one on the list I had to look at something that changed in position depending on if I had a trinket or ring or something proc. It was frustrating to say the least.

So, I bit the bullet and enabled SCT & SCTD again because it gives me this nice printed proc notification. However, it's buggy because it won't let you open the options menu to change your settings, and currently I'm getting this obnoxious chime sound every few seconds consistently when I'm under 30% HP or mana. Super duper annoying.

Anyways, it's going to take a while to get these kinks worked out, and I really hope to see my dps increase as I get more comfortable. Hopefully mentioning some of these issues will help you fine tune the little things to bump up your dps a bit more.

Problem with dummies is some spells don't work effectively on them(VE for example) cause they only have 1HP

I imagine that might cut longevity testing a bit

You know there are target dummies in IF (at least) that you can use to test, instead of Dr Boom
