I think that the constantly evolving and changing DayZ Standalone is a game that has great potential with the HG community.
I'm not necessarily the most active person in HG for someone who is not in it, half of you who have never player jailbreak don't even know who the hell I am, but I think that a DayZ private shard would be a great addition to HG with the many benefits of private shards.
The already half existing public shard has nothing proprietary to it as opposed to a potential private shard which would be a great way for the community members to play a great game.
