There's been a fair amount of discussion about this over the past few weeks and months, and its even discussed in a fair amount of detail in the OP. Please do more research before posting. Thanks.
Does anyone else have serious issues with energy capping as of late as combat? I used to be able to time my killing spree in such a manner that it didn't cap my energy but it always does now. Also when bloodlust and/or adrenaline rush is up and I need to use a GCD on something like tricks of the trade, it's very common for me to cap on energy because my regen is just so fast. The way I understand it, energy is predicted to never cap when predicting DPS so this is a bad thing. Am I doing something wrong?
For this reason alone I switched back to assassination just because as a single target dps spec it is much easier to be "optimal". Tips, suggestions, etc would be very helpful.
