returning player...some questions
No information has been released about character slots. Your guess is as good as anyone’s.
Nothing mentioned about using anything but DX9.
There are several ways to use Skill Points for Gold, as outlined in a few threads here. It is often suggested to keep them, though, as they may be useful in the upcoming expansion.
Welcome return, and good luck.
1.) You can try to convert skill points through the use of mat conversions. There are some sites out there that you can google “skill points to gold gw2” , but I haven’t used it in awhile so I don’t know if the data is fresh. Check prices manually first before trusting spreadsheets/websites
2.) No information on character slots, but it’s suggested to get 800 gems before the release
3.) No word on it.
