OK. Rookie who joined a little after this was removed giving his 2 cents.
I'm of the opinion that it should remain implemented, people who say it makes those who would use it put more effort into role playing sounds kinda stuck up.
Not every one types at super speed, some people would like to make sure that what they want to convey comes out legible which during a traffic stop (Navy or Pirate) which is hard given that the one who was stopped may bolt at a moments notice with you ether dumping your dialog that you were typing to be able to pursue them, or sit there typing in a near panic because they are now getting away, thus causing typos which in MY opinion hurt RP more, the dialog which is vital to being able to engage due to the rules of engagement see 3.6. Look, I can see where you're coming from, but I also see the fact that it's cons are so minimal compared to the pros that it's not hurting anyone other then those want to use the enemy's time typing to bolt.
I feel that something like setmessage doesn't hurt anything, so might as well leave it alone.
