To what do you attribute those spikes to 10 millions?
Could it be millions of players hoping for a return to a simpler, more rewarding game like WoW used to be Vanilla thru WotLK
I certainly think so. In fact, I am betting on it. WoW is the quintessential MMORPG... and it is timeless. The story/lore, the concepts, the mechanics (as they once were) are just as fun today as they were at it's peak. It is the idiotic developers trying to re-invent the wheel that has harmed the game drastically.
Classic will prove this... especially8 when it rolls over to TBC and WotLK.
