D&D 4E Any body have a 4e style disarm move?

[Garthanos]

Well, when i want to play a character who does massive knockdown and trips, I bust out a barbarian with rages and encounter powers that knock prone a lot. Knocking prone -is- a powerful effect in D&D, it's one of the tools a defender uses for stickiness. Being able to do so at-will would be extremely powerful in the hands of a defender-class... it's something I'd be very weary about.

After initial confusion, oh I see you were responding to somebodies idea of totally free-form move construction.... you needed to quote something.. "You slamb them with your shoulder and when you miss it is you who are prone and at the enemies mercy"... oh thats a different post, although a more recent one. or no stunts of a given effect can only be done once per encounter... oh yeah which post are you reacting to? ;-)
