Maybe for beginners, tests and special robots we should set aside some more time for fun-fights and demos.
For the Raptor competition it seems most of us agree with a 1KJ limit and no restrictions on parts.
Right now that would be the same rules as for Feathers.
The only difference might be, that with Feathers the arena determines the limit and with Raptors the result of the previous event.
Again... this is just an idea and interpretation of what I read here.
