Unrest is quite fine, but it depends on the time of day you play. The zone
needs 30+ people in it to be playable, with a group in the ghoul magi room.
That room is the key to Unrest, as pulling down the back stairs will usually
agro that room. It's also best to have a group in the tower and the bar if
one is to be camped as the other room will agro through the floor/ceiling.
Bats, the reanimated hand and a few things by the ghost room will see
through invis to undead, otherwise it's a necessary spell for moving around
in the house. Outside of primetime I never see enough people in there to
make it worthwhile, and in primetime it's camped. If you don't mind the
faction hits (who needs to go to Surefall or Karana druid rings anyway :p),
or waiting for a spot to open up, the treants in South Karana are cash and
experience city, just keep the level 30 and 31's outta your group. A bubble
of experience and 30pp an hour is minimum I ever made there (alot more with
just 4 level 24 casters). Last summer Cazic was quite fine to level in, but
now all I see in there are trains (all the fools from CB who never learned
to not make trains I think have gone to CT now). Was used to only seeing one
train there an hour, last time I was there saw em every 5 or 10 minutes
(about what Unrest been averaging too). I went to High Keep at 29 then
(never been there before and my guildmates recommended at) and hit 30 in 5
hours in the warrior room. Walk in, give the working with an enchanter 101
speech, start splitting the spawn, start yelling at groupmates not to attack
mezzed mobs (taunt them please until they attack like I said 3 times), split
the spawn nice and wide, relax and make experience.
