I seen a thread on the wizard forum asking us whom choose wizard, "why?" and it inspired me to create similar threads for the other classes. The idea is that, through the community posts, it will sum up some of the major (and minor) draws to each class. I, for one, would find this especially interesting since I have only briefly looked over the non-wizard classes but intend to play them all.
I am not just looking for answers based upon build/class strengths. Answers based upon something purely cosmetic or an opinion derived from the feel of the class is perfectly fine. Its all a part of understanding the general appeal.
