pause your queue? that makes zero sense. and what should other people do while you are paused? the system works like a line where people go to line up for things. everyone is in line for their instance.

so scenario... the DF hasn't matched even a single player with you yet. you click pause then lose your place in line while others pass you up. no different then simply withdrawing till you get back.

scenario 2... you already have been matched with a enough people to form a partial party. so now what? we pause them too? not only do people now pass you up in the line, but they get passed up too.

sadly we can't exactly ask the person ahead of us to hold our spot in line. however, this "pause" would FORCE others to comply. we can't force people to wait for us. all-in-all i don't think a pause would be useful anyone.
