MMORPG games with class switching?

Hey everyone, just wondering if anyone can recommend MMORPGs where you can switch classes for your character, similar to Phantasy Star. I played Phantasy Star Universe before and enjoyed it for a while. It got kind of pointless after a while since you did the same usual missions for exp and money, and there wasnt much other content to enjoy. What I really liked about it though was that I could change my character class on the fly, and it made me somewhat more attached to them (as well as the character design). I also liked the fact thatI didnt have to start from scratch when I started a new class, and if we needed a healer/gunner, I could change in 5 mins and still be able to participate in the same level mission.

The only other games I know of that has class switching is FF11 and Silkroad (I think). I tried FF11 but couldnt find the patience to play it. It just felt really slow paced, the combat and the grind. So I basically passed on this one. I played Silkroad a while ago. Tons of botters and playing against players who were beefed up with mall items was somewhat a turn off to the mediocre game IMO. I like things to be more even and fair.

So anyone knows any MMORPGs titles, whether its f2p or p2p, that has class switching? Thanks.

After a certain point in Guild Wars you can change your secondary class to what every you want. Each class comes with a large number of skills. There is nothing that says you must use skills from your primary class. For example, your current character is a Ranger/Warrior. You decide the bow isn't for you, you can replace all of your ranger skills with warriors skills and keep going.

I guess I'll give guild wars and lineage a go. Thanks. If there are any more recommendations please feel free to tell.
