Allow me to keep this quick:

Whenever you group for PvP this problem is initially not present, but whenever you reform your party after a Warzone (which, is something else that needs to change (I.E. regroup automatically after leaving a Warzone please)) you try and queue and if someone doesn't drop their current queue then the entire party must leave queue, re-queue as group, and repeat until everyone is queued together. Not a game breaker, but is an ease of living asset and would be appreciated.
