I find it interesting that there seem to be two points concerning the CH4 professions.
1. that their may not be new ones
2. that if they are they must be completely different from existing ones.
I wonder has A-net considered introducing a new profession but instead of adding new attributes maybe mixing some of the current attributes.
Priest of the Claw
//downside is that beast mastery is the only offensive capabilities
Blood of the Earth
It may seem silly, but I think it would add some interesting things and keep A-net from having to constantly introduce new attributes.
