Ok right before my balance was about to single big ben (i had crowns so it was all good) i though why not have a list of people waiting to go in. Not much differnt from pvp were you join the instance list and when it gets 4 players matches up they have to accept and poff all inside the instance. this would be good for players who dont have many friends or friends that are not on. These would be by the instance on a pedistal just were the instance sigil stops.
I like the idea, although you might have to think of a solution for people who want to do it solo, such as grandmasters and legendaries. It will be loads easier to farm and to finish quests when you can fight with other wizards that have the same quest. -Luna0616
