According to IMCGAMES TOS Team's public announcement on 2015-10-30:

6. Can you also open separate servers for the fans from SEA and EU regions?
We don’t have plans to open them at the moment, but when more fans from these regions join us in the future, we will consider opening separate servers for the fans from those territories.

I believe there are more fans in the SEA region than IMCGAMES appreciates, so I would like to raise awareness. We have a large playerbase that will continue to support Tree of Savior.

 Please show your support and sign this petition to raise awareness.
