What's basically hard for many to understand is that the different playstyle they're hoping for a new job to bring will be mostly just another visual skin over the existing roles.

Personally I don't have strong feelings for new jobs either way.

It's good that they add stuff because people want it but will it really bring anything new to the game besides slower developement. ( pvp balance, all levels of gear and added need for more weapons in each future patch from now until the end of arr)

I just feel like there's very little they can do in the form of new jobs that won't feel like a disappointment.
Having said that some jobs fit better the "only 3 real roles" format than others.
