Oh this is too funny.
2.0 lifespan was from April 2013-December 2014. I wonder why there was more content, maybe it was because there was over a year of updates?
If you are expecting a ton of content after a major expansion come back a few months before the next one you obviously don't know how MMOs work, I assume you were expecting 6 HM and 6 tacitcal flashpoints, 4 Operations, two bonus questlines, and 5 sets of gear at the start of 3.0 though right?
