Oh so the whole argumenet boils down to "I wanna play an MMO only 1 month a year" which....
1- is not how MMOs work
2- if everybody was like you they'd have failed financially 9 years ago

MMOs give you content in a way to keep you playing all year around and always subbed/logging (yes, mmos without a sub do the same, they even have login rewards to keep you logging every single day). If you wanna burn huge amounts of content all at once and then leave, maybe offline games are more your thing.
