Well you have been charging for tanking services so you should have the gold for it. I have never charged anyone for tanking in any way shape or form, I find the idea of charging someone for tanking to be stupid at the best of times and I have mained my tank since the start of classic.
Thats odd most of the people who I see who are anti RDF have a tendency to tell people to join guilds instead of doing things like do GDKP…
