I leveled Rdm second after my Blm, which has been my main since beta, and I'm pretty disappointed with Rdm. Sure, it was fun at first, but I got bored by its very simple rotation, which doesn't even get spiced up at 70, very quickly. From the second you unlock the class all the way up to max lvl you're just doing the same things. I feel like there's some complexity missing, which is incredibly sad, like there were chances missed.
Just a personal opinion and I'm glad you found that you like it and hope you'll keep enjoying the game.
