Nuke kztimer public servers are statistically more popular than gokz ones
Cybershoke is almost always packed with players and it's GOKZ, same for south east asian kz servers which are GOKZ, so it's not necessarily true. It just happens that KZTimer servers were the first to exist and it steamrolled from there.
Nuke which can be explained with kztimer having a more cozy feel and atmosphere for public servers in terms of UI and chat behaviour and some other stuff
It's always possible to give players ability to customize their own experience and UI even when they are in the same server.
Nuke this way new players can have the fun public server experience that we all know and appreciate, with the incentive to grind in order to gain access to private servers when they reach a certain rank (could be decided by server owners), at which point they can move on to more hardcore style of play
This is not how all private servers work though, some are exclusively for friends, some are exclusively gatekept behind ranks, some are paid VIP access. Grinding on public doesn't mean you get access to the private servers, and it also shouldn't be imo.
Nuke too many global maps currently
Don't worry about it source 2 will get rid of literally all maps.
Nuke unenjoyable chore for good players to finish all maps.
Good players don't have to finish all maps, it's not like it's an obligation that good players suddenly have to fulfill or anything. This part doesn't make sense to me. If you want to be a completionist, there's no way around dealing with maps that you don't like, it's just how it is.
Also there's few incentives for server owners to host public maps when they can host ranked maps instead and attracts more players and I don't see why you should gatekeep players from playing ranked maps that aren't in the public pool. And this last "global map" pool just seem like non global maps because there's no WR or map completion or point so there's really no incentive to play them at all.
Nuke all global servers would be under direct control of the global team,
This is just not feasible unless the global team is obscenely rich (last time I checked they aren't), the cost is a HUGE problem and even KSF can't manage to make their servers as widely available as KZ. Disregarding the cost, you also need someone in charge of each region to keep it running, because the maintenance and development work is immense, and then there are problems like you can't manage chinese servers if you don't even know chinese. It's an absurd amount of work for a group of people that doesn't even exist yet at this point. I do not think KZ being centralized is the future at all, especially when the whole reason why the global database/API worked in the first place is because of the gamemode's decentralized nature.
