Yesterday I was playing in The King of Ashes mission and a person with all 3* gear joined in and he wasn't a Vanguard. I read people must have a 5* gear equipped in order to attend a mission rank of 8 and above.
So is this a bug, can people bypass it with invites, or did I miss something about equip limits?
I don't believe the equipment limit has any effect on what missions a player can join; it only effects what * of gear the knight can wear..
