as we all know the old lfr system suck.
queueing for lfr 1 by 1 is not only time consuming, but can take up to several hours of our time.
what i suggest is to implement the same system they using for scenarios and dungeons already,
you will be able to queue for for any of the avilable wings same way you queue for specific dungeons,
once the queue pop your invitation to the other lfr wings will be halted however your place in the queue will still advance, when you finish your corrent lfr you will be offered a new wings if the group is ready.
will be really happy if anyone can post this suggestion on us forums
