I know a lot of people are not a fan of how easy the job is and how it doesn't pimunish you for making mistakes, but that to me means they got work to do on the other jobs. They were able to design RDM and SAM from the ground up and had a totally different as well as effective design philosophy with them that they should be easy to pick up and the abilities should be easy to understand. This is something they are trying to do with the other jobs, but are stuck having to keep them functioning similar to the way they have or end up alienating those who have played said job. As such RDM and SAM being brand new get to be the gold standards of this new design philosophy and the other jobs end up feeling clunky by comparison.
