That is literally just the president directing WoW related inquiries to Hazzikostas, who is much better suited to answer such questions as a game designer as opposed to executive staff. That doesn't mean Ion is free to decide by himself the business model of the game and who it caters to, especially if it's at the expense of profit as you keep insisting. If internal data shows that the design of an upcoming expansion is detrimental to making money the president will be informed, and let's just say his 'input' will carry much, much more weight than uninformed internet randos like you or I.
It is honestly quite laughable that one can think a lead designer for Blizzard can blatantly put his own little fetishes above profit and get away with it. Everyone from Ion to Greg to whoever was in charge before Greg designed expansions with profit as the top priority, it's just how corporations operate above the indie level. They just didn't know that stuff like borrowed power, mission tables etc. would be received poorly by the community.
