When Factions came out, I made a rit and a 'sin. Played the rit up to about lvl 6, just wasn't gelling for me so I switched the 'sin and used the rit for storage.
Managed to complete the game with the 'sin but, boy, what a chore - definitely not my favorite prof. Never quite "got" it, so I wasn't terribly good, had to settle for being just kind of meh. Not to say that it can't be played well by a skilled player - I watched one solo Scareater 6 times in a row while I just stood there observing.
Anywho, a few weeks ago I decided to dust off the rit and give her another chance. Got to lvl 20 and still was feeling that I didn't know what the heck I was supposed to be doing. Kept plugging away and finally started getting the hang of it; once that kicked in, I really started having fun.
Not claiming to be the world's greatest rit (yet

You know, you hear some people say that rits are boring but it's turned out that I'm having a blast with mine.
I had a similar experince with rangers, too, btw - my very 1st Proph char was a ranger but I sucked big time and eventually deleted him. Then I needed a new mule and made another, figuring I'd never be tempted to play him. Eventually, though, I did start playing him and, once I started to "get" it, I came to really love playing him.
I should probably give my 'sin another go; maybe with a little more thought and insight, I might find that I can be a bit more effective and, so, get more enjoyment out of it.
So, nothing really earth-shatterring in this post, just thought I'd share my experience. If there's any message, it would be "don't listen when people say such-and-such prof is boring". That might have been their experience but you might find it's the most fun char you ever made.
