Detrimental is my skip the fun.  I just got a new horse out of the armory (Champion Cataphract) up until then I had been using the Arabian, I wanted to swap them out.  I ran at the enemy and left the server, I did not damage anyone, and rejoined with the new horse and played the round.  The way I understood the double spawn rule is, if you die or kill someone else, leave and respawn, then you are in the wrong.  Correct me if I am mistaken, or ban me, either way this is what happened.
