Currently there are players who have expressed frustration with the way grapple works. It has been laid out how it works in the Theme topic about grapple, so I believe it is ok to mention that it uses Martial arts and Brawling to resist once the grapple is set in.
Would it not be viable to have a command to reverse a grapple so that the grappler is now the grappled? This could incorporate new Martial arts uses too and opens up a path for Wrestling and BJJ fans (which I was surprised to see a lot of players are martial artists outside the game) and lead to potentially cool scenarios.
