For the story of Warcraft as a whole it's not needed. In the RTS games we didn't need this powercreep. WoW doesn't lend itself for a good story, Warcraft as RTS was a whole lot better in that regard, the only downside there is that as an RTS it didn't have as much opportunity to flesh out the common folks' story as opposed to armies and leaders.
