I like to heal and have a pet to help with soloing, so Warden is my main, but that's another thing I really really like about the progression is that all classes can tank, heal, or DPS with so many different abilities based on the weapons you use.

Obviously there's more meta picks, like a Templar was for tanking (might be out of meta by now), etc. But for real, the systems are very accomodating to build variety IMO (again people will probably disagree, but im not playing the game hardcore. Just for funzies)
