If we assume Legion launches in July (which at this point is a pretty optimistic guess) we will have had a content drought of 13 months.
For these 13 months we paid 169€ (13x13)!
In other words Blizzard earned money comparable to 3 1/2 full price titles without delivering ANYTHING.
And yet they throw more F2P elements (ingame store, boosts) at their players. Absolute disgrace.
WoW has become a laughing stock, a total ripoff. It's by far the worst bang for your bucks out there - ever.
