Skipping Missions

In Factions you actually have to do the main story line to get places, unlike Tyria.

Nope. To advance in Factions you HAVE to do missions. Now..I did consider the use of Necrotic Transversal for those areas in Kaineng you don't have access to but are in a lower level of the same zone that reaches out to the southern more zones to get to Maatu Keep, then head to Tangle Wood, go outside and kill something/Nec Transversal down there. Never tried it but considered it though.
