I think enough time has parted since Horde and Alliance have been able to join guilds and do non queued dungeons and raids together that maybe it’s time to revisit queuing for random dungeons.
The negatives at this point are pretty minor besides maybe a few faction die hards being a bit pouty about the prospect of another faction of players joining them in the dungeons but honestly blowing through your time walking dungeons or whatever random dungeon you queue for the interactions between players is minor as is unless someone fails a mechanic.
LFR I don’t really see being an issue but maybe someone else can provide insight on that as I’ve only very recently come back to WoW again. I just find it pretty annoying I can’t join my alliance friends and knock out some time walking dungeons with them.
