Martini,
I am a bit at a loss after your last remark. I believe I have pointed out that the movingphase would not just loose a variable, but also gain a variable. I also believe I have pointed out that Team dynamics is not dependant on this shoot-at-nearest rule. The dynamics you describe are perfectly valid and similar good tactics without this rule. If you feel the shootingphase is not ment to be a thinkingphase, I dunno what to say to that other then: I like a game to challence me, and having to think through your options in the shootingphase poses an extra challence, while at the same time this does not lower the challence in the movingphase.
I have presented several reasons to drop this rule. I have presented alternatives for at least partly incorporate such rule consistent with other game mechanics. I believe I have countered arguments, that this rule would be neccessary, or that leaving out this rule would degrade the game. If you say you see NO valid reason I assume that you don't WANT to change this rule, nomatter what reasons are presented. And that's ok, we both live in a free country(I hope). But say so, admit that you like the game as it is and that you see no need for you to change it in this aspect.
