In BfA, there are some faction specified world bosses from Warfront and currencies like Honorbound Service Medal and 7th Legion Service Medal. So if you track both Alliance and Horde character, two line will be shown and half of space is blank.

As there seems to be more faction specified stuff like Battle of Dazar'alor LFR with different ids for two faction but same bosses, I wonder if we can merge two lines into one like WoD's Drov and Tarlna.

probably a good idea, yea
