Chrome Remote Desktop is the best free remoting tool that I've used. Teamviewer is fine but it leaves those stupid popups on your PC when you end your session and isn't as smooth as Chrome. I've heard good things about Splashtop but last time I checked, the mobile app wasn't free.
The only thing different about the classes would be a maybe a few settings and the combat routine. There's already a combat routine forum... are you having trouble with something?
