Reading through these forums and other places online... basically every class has complaints. Looking at them, yeah there are nerfs/changes/etc..., but a lot of it comes down to classes being associated with certain roles. Templar=healing, NB=rogue, Sorc=Sorc, DK=tank. Lot of people flipping out about a certain class not being the best w/ a certain weapon/role.
Looking at the class skills any class can fill any role. Think this was ZOS`s intention w/ the ill-fated "play your way" tagline.
1.6 is a perfect time to break the pre-conceptions and rename the classes. Call them Lightning, Shadow, Flame, and Light... or anything that doesn`t imply a certain role and I think you will find a lot less complaints and more build diversity.
One of the best things about ESO is the ability to switch up any class and fill any role and for new players it would be great if this was presented in the beginning to set that frame.
