You make a few mildly good arguements, and then totally ruin it by constantly referencing the fallicy of implying that "the majority of the playerbase" has quit WoW over their change to Purple Pixels and raid loot.
WoW has lost hundreds of thousands of people. For almost as many reasons. Purple Pixels and Raid challenge difficculties are a tiny fraction of the total varying reasons people have quit WoW. And for every handfull of people who leave, there are handfulls of people who join. There are also handfulls of people who burn through an expantion as fast as they can, and then just leave till the next one comes out. Trying to pin WoW's success or failure on a single item like Raids is about as dumb as trying to pick a single ingredient out of a Meal with 100s of ingredients and claiming that "this one" is the one that made the meal work.
It would actually be fascinating to see the numbers on exactly how many people got one of those Wolf Rider statuettes for staying subbed the entire 10 years, cause I bet that number of us who have played for the full 10 is probably shockingly tiny compared to the number of people who have played WoW over its curent lifespan.
