You’re welcome to subjectively disagree, but until any of these points come to fruition because of gamepass… 
Which that’s another thing, how do you even know if those things will happen because of Gamepass anyways? They would happen without gamepass anyways if it had to happen. This whole “Gamepass is evil and will make games worse” has no grounding in reality and just seems more or less a scapegoat, instead of looking at the issue here.
WoW has been in trouble for like how many years now? What would Gamepass actually do to make it worse?.. Even if we believe the whole fake numbers people love to prop up from guess work and so on as true, that being say… 2 million, how would giving people another way to play WoW, hurts WoW in any real way? More people would be coming in.
And the minority of people who are quitting over unfound fears of Gamepass is just that. A minority.
My previous topics on Gamepass says otherwise that i do dig saving money on genuinely good products.
