Only add the Nexus Update to a small portion of test servers
From what I have heard, the nexus update means that you will be able to travel to a different, small map through ferry terminal.
Which basically means, you have a potential of needing to cover the whole map length 2 times if your target is in a really inconvenient location, and even if you can bring a minicopter through the transfer, you will need to land in between and have a good chance to be killed.
This whole thing just sounds incredibly annoying.
Having everything on one island is a thousand times better.
Deepsea is different because its a limited time event like Cargo, but splitting the permanent map in 2 is just gonna be like living in a messy house.
Please just add it to a handful of servers like Hardcore gamemode so people can choose not to play with it.
