What he is trying to say, is that if it gains enough traction, anything is possible. If people, and by people, I mean a LOAD of fans like the idea of Emily being a Lindholm, then Chu may do it considering she is a clean slate. How can we say what he will and will not do? Fans also wanted a support who can suck like a vampire and lo and behold, Moira is made. Also, people wanted LGBT heroes and yeah they gave us that too.
Also, we wanted a Talon Tank and they incorporated that into lore. They didn’t have to do it. Not at all. There is no standard or it is no mandatory saying that both “the good guys” and “bad guys team” needs a main tank, but they did because fans wanted it. Fans have the voice and whether it is small lore or game related, they will incorporate it if the fans want it.
Michael said in an old interview that it is we fans that make the lore and they just sit back and work around us to make that a possibility.
