The LFD queues do not place you in a party with any other participant that has not queued with you from your realm until the group is full and all participants have clicked to enter the instance. This is adding another layer of protocols to group people cross realm before the LFD tool is used.
I wouldn't consider rerolls as gas costs, more like special hunting trips with a fiery bromance. I also wouldn't consider realm transfers gas costs, thats more like deciding your friendship means more and picking up to move so you can do everyyyyyything together.
