Guild Wars 2

It seems that when I run out of lives I can just go back to the hub and reenter with my friends. Is there any negative to this? I sure don’t see any. Seems to render continue coins useless unless you are playing solo. Am I missing something here?

Technically, yes. That is how it works.

There is a disadvantage though. I believe you only start with 1 life if you do it that way. So if you die often you will be repeating this process a lot and slowing your group down.
