I don't see much difference between "engaging red" and it's "/l1" counterpart.
If people don't want to role play,they simply won't.
Plus,preset messages are useful in more than one way.
Imagine you are in a fight,you can just drop /g1 which your earlier set to show the sector you are in.
Yeah sure,it will make people type more,but in the end of that,nothing will be changed.
