Well said, good sir!
As to the point of the OP, and that new players should be welcomed to try anything, and they don't really need pushing into one direction or another. If a new player wants to test a concept, they can easily just do the tutorial and DFB Trial and by then they usually know if it is something they like or not. Total time invested: maybe 30 minutes, depending on how long it took to create the character.
I personally love trying new builds, especially the ones that seem silly or not conceptually wise. Some of these characters I build for TFs and Trials, some for going back and soloing for content, others just for AE, and one was built specifically for me to run Ouros missions (it's an RP thing).
My point is, as some others have said, anything can be viable (emphasis on can). It really is just dependent on how you want to play. And the only way to learn how you want to play is to play the game yourself and learn from your own experience.
It really is that simple.
