this is always an interesting decision when i start a new MMO as for me it is not really about role but more play style, however i tend to avoid tanks for reasons i will get into later. for me what is really important is how the class accomplishes it's role not what the role is. i like classes that are reactive and fast paced, for example in GW2 i found myself always coming back to the D/D elementalist as both there damage healing and survivability revolved movement and being in the right place at the right time. because of this i find i usually end up in DPS roles as traditionally healers and tanks mostly stand still, but with Wildstar and how healing looks like it will work i could see myself being really happy there as well. all in all i think i will find that i will pick a class and play style and fill any of the roles that class can fill that are most needed. on that note any speculations on which classes wile be highly reactive and mobile?
