I appreciate your post and wanted to drop by to say the following.. Every person will have different opinions about what works best for them. However, I encourage everyone to try multiple classes and elite specializations out before committing long term to one or two classes.
I primarily played a Guardian as my main since GW2 came out. Firebrand Guardian felt awkward to me and didnt have good flow. However, I recently dusted off my Mesmer, obtained Virtuoso and fell in love. I am finally working towards a full set of Ascended gear because I enjoy it so much.
