The issue here is simple.
None of you want to be a member of a guild.
You want to queue in a raid finder, and be given people to play with.
Guild Wars lets you be in FIVE guilds at a time.
Want to find a strike?
Try this.
"Hey guildies who I know and am an active part of your community, Who wants to do a strike?"
<9 people you know say yes>
<You do a strike>
The problem isnt that GW2 doesnt facilitate being a loner, its that you all are antisocial AF.
