I've answered this question a lot lately, so just check the first few answers, but to sum it up, if you are willing to put in some time, and can find a few people (if you play every MMO, certainly you should know someone) to take you in, you will not have a difficult time catching up to at least compete.
You are right,there are not a lot of new people, but it is not like there are not any either. Most classes can solo to 50 okay, although it is funner to do it with others. In fact, leveling is fast enough now, that keeping up equipment is the bigger problem. If you odn't have someone to help you out financially, or if you don't eBay cash, this is a bit of a problem.
I'd recommend trying out the free trial again, and see what you think. Try to find a friend to invite you to a guild. That will help a lot.
