I basically played back when the game was released on Steam, mainly played for the hat for TF2 but then I grew to love the game as it reminded me of my first video game, Legend of Zelda: A Link To The Past. Since then, I haven't played cause of issues with my old Steam account and I finally decided to just make a new account and play again. Spiral Knights is still as fun as I remembered it being but it's changed and I was just wondering, I havn't played since...I want to say July or August 201, what have I missed?
Also, has the regen time for Mist Energy been lowered? It feels like it comes back faster than what it did before.
If you really want to know what you've missed, then just read the Announcements forum, for a detailed list of all release notes. Or go to the wiki, search for release notes, and read them there. You will get a much more reliable, thorough picture of the changes to the game, than random forum posters will give you.
