That's disappointing to hear, I wondered if those of us that love it so much are only a smaller subset. I remember it only being around for I think 1 day last time and thought that might be the case. If I had to guess, there are two main reasons why more of the general population don't play Blitz:
The quickly moving zones mean people that aren't smart with rotations die to storm more often, and that isn't fun. Maybe reworking blitz to have slower storms and even more mobility would help.
The sweatiest of us play ONLY blitz when it's around. It's just so much more fun. But this means it isn't fun for casuals when all they encounter are sweaties.
Look, according to my end of season recaps I've been farming around 2 million materials per season since season 3, and I am so, so burnt out on farming. Yet my building skill has grown so much since then, I can do so much more than before yet the farm rate is the same and the hours I spent grinding building skill feel wasted. For example, I NEVER thought I'd be able to do something like this on controller when I was stuck on combat pro, but now that I can do this with builder pro, the farm rate just doesn't suffice: https://www.youtube.com/watch?v=EIYyVznhfxQ
I pretty much can only stand playing Fortnite when the pop ups are around and most of the time I miss the limited time windows for them. I really hope y'all are considering upping the farm rate in the main game mode, at the very least.
