It makes all the sense in the world. SAM and RUN are still used,... still relevant. They don't get a boost. The other jobs are not used by the community mostly and need an upgrade to make them accepted again, so they get it. It's that simple really. If you say that SAM is not relevant, I am not sure which game you are playing. Can another job easily solo the 4 and 6 step skillchains necessary to pop vagary NMs?
