As a vega player i am happy a merge is happening. Hopefully we can change server settings for Deut in debri aswell when the merge has happend. there is a lot of players that want it. I can see many people feel disappointed in the choices offered, i would probably be disappointed aswell if i had to move to servers that had unfaverable settings or players 100x your size.
People making comments about all their moons being blown up, in theory yes, this is very possible, even in the same night. In practice this takes a lot of planning and coordination and i have only seen it happen once and that was on me in this server and its been over 2 years ago. Its very demanding and not so easly done. If you fleetsave propperly you should have little to fear from anyone.
The game has felt very stale the last few months and i am happy anything is happening right now.
Any new player will adapt to their new situation as they did previously.
I do feel perhaps its better to make all unis exodus unis and create 4 or 5 complete new servers with settings people want the most. This way people who are stuck in target unies get to choose aswell
