The things that I hope they fix is the lousy loot that is in the more dangerous zombies. Kill a Hawaii zombie and you will get nothing, same with some others. Big Momma gives tools, shovels and such and is worth fighting. Watched a lot of videos and there are lots of complaints of how TFPs must not play their game or they would know there is lousy loot so why fight the zombies, just hop on a bike and ride away, or run away from them and do something that gives better loot.
As for seeds, what a lot of players don't realize is that there is more than one spawn site. Spawn in the desert, or in a burnt forest near a burnt city, in the plains and have two or three days to walk to find a city, just a building here and there and get lucky they give food/water and find yucca in plains/desert. Corn in plains to have to eat; snow berries also to eat in forest and snow biome. Or a great spawn site with several cities close by, desert in one area for yucca and aloe and plenty of corn, potatoes and berries you can grow. That was in just one seed I was checking out. I'm not complaining about it, I expected that, but some don't (and should).
I don't think anything needs to be changed in the minibike, too many remarks, here and in comments on videos of how hard it is to find a decent engine and battery. Most are tan or yellow, and the higher quality are almost worn out. I had one where the deer outran me. And if a zombie had been feral, it would have been able to run me down. Remarks of how hard it is to find a bike and crossbow schematics.
These aren't from me, I get a lot of info from players who comment on youtube, but never post on the forums, which I think gives a good idea of what the casual players are dealing with. Most of those who watch youtube or twitch are of the younger generation, ages 15 to 20s. There are a lot of teenagers and adults in early 20s who play the game.
Ziplines, I was looking forward to, behemoth, not. It doesn't fit with the story of WWIII and virus due to _____ (whatever). Yes, I can see DNA research in trying to find a cure and the irradiated and feral zombies, but not a behemoth. And as for why, just like the smell had to be dropped and set aside for later on fixing, those could have caused problems in a more important area.
