Honestly I am the reverse, I wish they'd unnerf the turn timer. Unless I am mistaken it was shortened twice, or so it feels to me now coming back from a long break. I am roping too often and I feel I have no time to think. The first shortening which happened way back when I was still playing was probably ok but current turn lengths are just too damn short.
I think having this an option you can toggle in your preferences to enable speed mode would be a really great idea where you would only be matched against other players with it. However you might as well completely change the new Nozdormu if this were to be the case as it wouldn't serve a purpose aside from being a handicap for the people who choose this mode.
So you've been queueing for an hour an didn't find another Nozdormu player... And you still don't understand why this game really doesn't need a Nozdormu mode ? Nobody would play that mode.
And those of you who think they would enjoy it, you'd get bored of playing a game mode where control and combo decks don't exist, where you constantly make mistakes because 15 seconds isn't enough to make some plays.
