Ok, I'm going to say something in here, there are alternatives to grinding at the GGG. They consist of:
The Sparring Grounds/Dojo - Here you can set your GGG rits, find those that have a single tree set up, and attack them with your non damaging/multiple attack rits. You also have the chance here to attack the idlers here, using rits that actually kill.
The GoE - Here you now have Burns' Fight Club which is a good way of learning how to defeat various rituals using your knowledge of ritual setting. How do you get that knowledge? Attacking and seeing what happens. Learning from experience, not just 'no matter what, I know I'll win, so I won't do anything different because I don't have to'. That thinking screws up your mind.
Everywhere else in MD - Go out and RP, do something other than sitting at the same scene. Please... for your own good... go outside the GGG and PLAY!
