I am apologize, cannot find the thread about zones for level 28's but would like to add what I have seen....I took my level 39 bard to Dalnir (sorry for any misspellings) and I am sad I did not see the zone a few levels ago. I would guess the bard would have done very well (exp wise that is) at level 34 or so solo, as it was I made decent plat and some experience. Of course, to an untwinked bard, not to mention my main, the plat may have seemed low. But I have also hunted ice giants in a group in Everfrost and saw no real difference in the money I made.
I have a 28 SK that I am going to run soon to the zone at some point, too bad there will be none there to greet me :).
/ooc My rating has gone from 2. something to a 5, many blessings to some, and Good Hunting to those that dropped me below a 3 :). Not sure what ratings do, seems to involve a filter of some sort. I am glad I see all and try really really hard to ignore some.
