Been playing since it came out and love it!!!! Recently it says the servers are down and i cant get in? Anyone having the same issue

Hello, can the game be played completely offline (no internet needed) in single player?

The power level quests specifically seem to be bugged in some way. I had both a 10,000 power quest and a 20,000 power quest. I managed to hit 38,000 power in my last match, yet neither of the quests were completed. Figured I would point this out, and hope that if there is a way to fix it, that it eventually gets implemented....

I note that 'minimum' requirements on the Store page, which my computer is good for. But there don't seem to be 'recommended' specs?

I have put in some time on this game, and noticed when you play solo, or even duo with a friend you only fight AI. I have yet to be matched up with an actual player opponent.
