Make PvE Challenging

I think Factions is the best example of a boring set of spawns. The reason factions gets (or got) frustrating...is EXACTLY the reason the OP suggests makes the game boring.
Really, factions doesn't require much more than a Minion Master. If you can brute-strength overpower and outman the mobs of afflicted, you win. Best examples: Eternal grove, Harvest Temple, quests in the Undercity, even the mob near Kaineng center, in the Pongmei valley near Maatu Keep, and in Sunjiang district.

Yes, that game will show you at least two challenges: the other team keeping their guy alive at the start of Vizunah and getting a good group in Unwaking Waters.

unwaking is done better when the other team is all hench.
