Thank you for collecting and posting this information. I will be returning to Runes of Magic after a long absence, creating new characters, and generally giving the game another shot. I found this post helpful in determining which class combinations to try first. Again, thank you.
Addendum:
Would it be possible to include some example screenshots of some of the different classes in action? I know it's not that important, and probably too much work, but I do think looks are part of it for a lot of players when determining a class. If they are included, I would put them behind a spoiler anyway, so as not to distract from the rest of the content. I just think having an example to quickly peek at while choosing a class could be helpful. Even without pictures, I still feel this post was very helpful however.
