"The campaign will focus on Zeratul as its main character.[7]
The protoss campaign will be based on diplomacy as the protoss factions splinter.[8] The player will work with different protoss tribes[9] and sects, helping leaders of some sects which will anger others.[10] Using units from one side may preclude using units from the other side[8] and alienating one or another sect may cut the player off from part of the campaign.[10] The ultimate goal of the campaign is to unite the various tribes into a viable, unified force that can ensure the protoss' survival.[11] "
From the wiki.
WoL helped in setting the stage for LotV by showing us that they are conflicting with the Dark Templar, so the worst you can objectively say is that their role in WoL dragged on longer than neccesary. It was not an excuse for missions, not if Blizzard intends to do something with them when the expansion comes around. Besides, simply saying that the Tal'Darim were a waste of space doesn't automatically make them bad. Several ME2 characters and the UED of BW were kind of pointless but they were still likable enough.
