As someone, and one of many, who completed the Y2 MoT before they were even released, I've got to say that it hasn't seemed as nearly a big a challenge as those MoT in year one.
No, it is not because it is easier, IMO this year's MoT were much more challenging than before but as the game has become larger and more content was released, moving from Year One to Year Two in Destiny has been more fun than ever but less challenging than when you start but very fun none the less. The more I play Destiny it seems the more I want to continue playing it!
For those who have completed the MoT already in Destiny, Congratulations! And to those of us who have been here since the beginning and have done both MoT, cheers to longevity!
For those who haven't done all the MoT yet this year, keep on working towards those goals, even if (to no one in particular *cough*) you lost your mic because you never thought you'd use it so you cant do the raid and are too lazy to find all the fragments, you'll get there!
To Destiny and its salty Community,
Your lord and savior, The Architects
