I think not allowing specific player targeting is wise, so no chance of foul play. I did think maybe there should be a 2,5k HP minimum for offie movement, to avoid moving low level, lesser skilled, wrong clothed or damager build players.
And from my pov, I've seen the feature both be useful and abused. Perhaps it would be helpful to have a chat prompt appear when the movement is activated, as in.... General XYZ has ordered the movement of offliners. I've seen a few occaisions where no one knew who did what and it takes some rounds of guessing for where they (offies) are headed. Also, in the instances of abuse, we can know who was behind this and perhaps towns can take action with demotion should they see it a problem.
