/nod agree on world merging issue should be polled in the beginning of this year.
but that's also why they announced super early. just to see the community's response. Sort of help us narrow down the options. But, it's really stupid. a poll in website is much easier...
now they probably will change it to another option such as you are free to choose, but when you selecting world your world choice will be at an initial pre-selected world? I donnooooooo

If not, just use rest of few weeks to decide which server to choose...
