I've played RO since the open beta testing, the character I ever made was a swordsmen, however since i was a complete beginner who had no clue on where to go or what to do, I never passed lvl 20 and was almost always broke... then I got attracted by how easily merchants could make money and tried to make one, but never passed the job change since i couldn't afford it
I experimented with a few first classes except mage and thief, even when beta testing came out for 2-1 classes. (I sucked at RO so badly back)
When I joined my first private server several years later (its still live so no name) I made him into a crusader. It was a shield/vit build so I had a lot of trouble leveling in the hard dungeons since very few people back then prefered to work with others. After trying Blacksmith, Priest, Bard and Sage, I quit for a few years until one of my friends became interested in playing RO, so I made a new character so we could play together, and I made that into an alchemist, which was an interesting experiance since they were so versitile at times (there was no trans back then so you alchemists could buy their ammo 500z a bottle excluding discount) and I eventually made alchemist my main character. Even when I moved and there was no alchemist shop.
