It would be really nice to have dedicated servers and a higher player cap from 4 to maybe 8.

Dedicated server, yes, but I like the limit of 4 players... Not too much going on, and gives a bit of a challenge! Otherwise, you've got that little yard too busy with 4 people exploring/crafting all the time. Before players would die of thirst or hunger, I would leave my son's low end PC on with a player so that I could join whenever on my PC and my son & wife join via Xboxes. That's changed now obviously, but it was also nice bc my son could swap between players/ devices without really "leaving" or quitting, etc. He would just dump the backpack out and re-pickup items etc.

To be honest I side with more players. It'd be nice to have some custom characters with little to no lines.  I have a lot of friends that play this and we would love to play together .

Also imagine if we could turn off player location markers and do a 4v4 grounded survival!

Dedicated servers or at least the option to host on a dedicated server! Annoying as hell for our group that plays across 9 time zones to wait on one guy to get on the main build. 

8-10 players would be fine on this map.

I'd love to run a dedicated server in a docker container, it would also be nice to have 8-10 players, it always sucks to have the fifth friend who can't join because the group is full.
