By turning off "Tactical retreat", one is making a statement that (s)he is a responsible, honourable player and therefore deserves a reward of some kind.

Possible misuses:
Misuse: "Tactical retreat" turned off while being online and turned back on again when singing off.

Solution:
Make it necessary to have "Tactical retreat" turned off for a certain period of time (minimum 24 h).


Misuse: "Tactical retreat" turned off only on planets with no fleet.

Solution:
Make it necessary to turn off "Tactical retreat" on all planets.


Misuse: Turn off "Tactical retreat" and go to v-mode.
Don't give honour points for players in v-mode.


For example:

By having "Tactical retreat" turned off on all planets for 24 h straight, you gain five honour points.


I believe it would bring a new strategy element to the game.
"Should I turn off my "Tactical retreat" and use all bunch of the unkown benefits honour points will give me, or should I turn it on, just to be on a safe side?"
