Far too late. And I mean faaaar too late... People were basically tired of this game when the follow up expansion of TBC came out (I can't remember the title, I only played the TBC one at the time for half a year), and that was 10 years ago. 10 whole years. Blizzard knew fully well they were fucking up 'cus they even stopped showing just how hard their cock was. Yes, they showed publicly how hard their cock was by showing public numbers of subscriptions, but when these numbers declined really hard, they thought it'd be better to keep this chart private but still shitting out a bazillion sequels nobody was really waiting for, but addicts being addicts they bought them all anyway.
Again, really glad I didn't pay a single cent towards this game, but I'm really, really happy they invested time into making a new patch for warcraft 3:TFT after so many years now, yeah, since February they actually released a patch for this awesome game. Now that is something worth investing time and money in imo.
