WildStar's latest WildStar Wednesday feature speaks to the idea of ways that cross-realm (server) activities will function. Players will be able to communicate, group and game with cross-server buddies in specially instanced areas.
If for some reason you are anti-social and don’t want to meet people from strange new lands, we will be accommodating you as well. Most of our cross-realm features will have a checkbox to say that you only want to play with people from your own realm. By choosing this option, our system will only match you with people who are on your own realm, allowing for you to make friends who you'll be able to continue to play with after completing instanced content.
There are some limitations to our systems, however. We sadly can’t allow you to explore the world as a whole with your friends; as the world would quickly become too crowded. But anytime you enter instanced content, whether through battlegrounds, dungeons, arenas, or
, your entire party will all be able to play together. There is also a limitation on being able to trade items. Because we feel the economy on every realm is very important to maintaining the economic stability of the realm, you cannot trade with your friends from other realms.
