Just for the record, I believe this question is the same for 5th and 6th edition; if not, please consider the question with respect to 6th.
First, the Grab maneuver allows the attacker to throw the character grabbed.
Can the attacker "throw him to the ground" (target falls) and maintain his hold by going to the ground with him voluntarily? (This would simulate the most common wrestling takedowns.) Or must I make a separate maneuver with grab (3 pts), "throw" (target falls 1 pt), and "you fall" (-1 pt), which comes to the same point cost? (Unless 6th edition Martial Arts will change this when it comes out.)
Second, some published characters, for example Diamond from Champions Universe News of the World, have maneuvers that combine the "normally considered offensive" maneuver grab with block (Diamond's "Grappling Block") and escape (Diamond's "Reverse"); does this mean that that the "attacker" can do this as long as he does not do damage (from crush or throw) until the next turn? (That is how I interprete it.)
Assuming the answer to +2 is yes, for the grappling block is a second roll required, one to block, then one to grab (only if the first is successful)?
Thank you.
