I went to veksar with my mage around 58 with my epic pet and it was pretty good. There are plenty of mobs in the courtyard right near zone in, and you should be able to clear most of it before repops.
There is also a named standing on pedestal right at zone in, can't remember if he drops anything good. The loot is decent coin and a bunch of weapons, not sure what they sell to merchants for.
It's a pretty good spot, however I always preferred nurga/droga. The mobs there seem to have less hp, don't hit any harder, and are super easy to single pull. These two remain high on my list of favorite dungeons (I still solo in droga at 63) and I found the xp to be as good if not better than veksar. Plus as mobs start turning lb to you, just move in deeper. Also, a bunch of named there who are no harder than the regular gobbies, if you run around killing placeholders and spawning named you can get some pretty decent bazaar-sellable loot.
