Warlocks also need to continuously respec and reforge for fights to optimize their DPS whereas all a shadow priest has to do is take their OS into account (partly different gearset) and reforge for Spine.
Instead, you can find the data analysis in the series I linked. Add to that they have a far more complex rotation (compared to for example fire mage, arcane mage, shadow priest, even moonkin) and it isn't an attractive class to play. They have been in decline in raiding. They are popular in high end arena, that is true. They are not popular to level. Warlock is still used in 25m hardcore raiding, yes. These people are good at mastering their complex rotation, and also DI is a damage increase. So what do we have? A class which is popular in high end arena, and remains constant in popularity in 25m hardcore raiding. Guess what, this is a terrible class design.
The 3 specs borrow a lot of spells from each other; in MoP each will have their own utility and mechanic. The main rotation from each spec cannot borrow anymore from other specs due to the new talent tree system and design of each talent tree. What I don't understand is why Blizzard wants mages to reuse spells from each others magic school but I do understand that is related to frost being either too OP for PvE or only useful for PvP.
Yes, it is. If you have played MoP beta the 3 specs of classes are all roughly equal in difficulty (but output and utility differs per fight in both PvP and PvE). The difference lies in the complexity the user prefers with talent and glyph system. Also, your example is between specs of the same class. If it were true for warlock, one of the 3 specs would be tough in rotation but higher in damage with the other being stable and mediocre. This isn't the case for warlock. Sub rogue has its place in PvE, but generally only used at Spine. Warlock, in contrast, constantly has to switch their specs.
What statement?
The article I quoted explains the points in detail and it has been a while since I read it. However it contained data analysis and compares.
PS: I don't give a flying fuck about top DPS on Madness, I know it is possible to skew the meters there and I know how to do it. It is the prime example of why DPS meters are irrelevant without proper context.
