I think the Hollows are pretty good as is, it is a hazard zone after all. I only have two complaints really.
1. It isn't really clear that you don't have to take the missions from Wincott. I have spoken to many players in game that think you have to complete them in order to complete the initial "speak to that person" mission. Just make it clearer to the players that Wincott is just a new contact and not part of a larger mission.
2. There seems to be a great deal of lag in the Hollows, I don't know the reason for this, but it is very common for me to run into groups of bad guys that just seem to "spawn" right in front of me. I have died a couple of times like this. I would be just running along and bam! This only happens to me in the Hollows and no where else.
Other then those two items, I think the Hollows is a rather fun place to go for a little excitment at lower levels.
