I think this point require a little clarification.
I am assuming that you meant Blizzard had to come up with abilities and talents for MSV from scratch. However, I suspect that people would misread this.
That being said, I found your OP to be clear and concise (and your argument seems solid). Nicely done. 
The only thing I would say is maybe add a little more to the introduction? Set up the problem so that people know what you’re talking about. I knew because I was following your discussions with Azagorod in multiple threads. But they might won’t.
