Another class to consider is an SK. A little less popular than the ones mentioned, but you can solo okay with them and you usually will not have any issues finding a group as a tank. They do not require a ton of gear to do their jobs and you have access to some really nice and inexpensive weapons as the plat starts coming in. Having feign death, invis, invis vs undead means you can go pretty much anywhere. As a tank/puller means you will not just be sitting in camp all the time and you will see other areas while you're exping.

All that being said, If you don't want to tank or primarily group, I would recommend a druid, necro, or enchanter in that order.
