Hello im a new player ISH so please if i may made a mistake pls be kind 
(also not very good at english sorry)
im suggesting a dungeon queue block on other players mainly on those jerks that solo kill the boss and hog all the exp for them self thus wasting my entry on dungeon which we all know we only have 2 per day or 3 if your a token user.
and players that use instance dungeon that purposely use when others not around.
ex.
at the start of run when you and other player start killing some monsters this 1 player will sit and wait for others to be far enough and not get exp bcuz you need to be close enough to monster killed to get exp (if my understanding of exp sharing is wrong correct me ill be happy to be educated 
.
blocking players
if i dont want to be queue with player 1 i will block him (you know when you right click the character you see a block option).
so when i queue i will not be queue with player 1 simple as that
