IMO i think this is a great idea there or more benefits to doing this as well.
Having people not able to rent public servers is a good thing! Private hive servers are by far the best way to grow a community and really connect with the players that frequent your server.
i know people like the ability to have there own servers and maybe switch between the two because you have the same gear. Understandable its nice to have gear on multiple servers without having to gear up another character. That is why there are multi shard servers however. For example, BWAF they have a multi shard server and a website, they really grew a community and a player base and you still feel as if you are playing public hive. Gents of novo, another great community. Multi shard server, so i think if people really want to grow a community this could be a great thing. Also, Private hive servers would have an increase in traffic, public hive is nice, i think it should be under management of Bohemia. It would be a default DayZ experience, and that is what public hive should be, IMO. I'm sure up front this may seem like a really bad idea and even an annoyance to the community but i think that its a better idea, keeping an open mind i think that this may be a huge uplift to the game and i for one am looking forward to this, if it goes through!
