Use this zone for more incarnate content and advance the story line with the imminent invasion of Battalion. I have been hung up on that for a long time and would like to see Homecoming tackle some serious lore and story advancement. Praetoria was nice, but ready for something new.
I do like the comments about more rogue/vigilante content which makes sense between 20 and 40. Lower unused hazard zones should get renovated for that content. I would like to see where the new Boom Town was going.
Zone optimization is good. i have far less crashes moving to 64bit client, but man that 32 bit client, 50 people in the zone and my computer gives up.
