The metadata could only show you how much people are using the ability, not exactly why and how much they are enjoying it. That's his entire point, and it's a very legitimate one. If you give me an overpowered ability I'll use it to get the most benefits from it, especially if I'm in a tight spot, but it doesn't mean I like its existence or how predominant it can be over any other strategy.
Funny thing ... I dont use the overpowered ability, bcs then the game starts to feel "just the same over and over" pretty quick. I presume its all about attitude. :P
I still dont understand why cant we change Race for our hirelings. Lets us play Githyanki as racist as they trully are!
