I totally support long range tactics. They are paramount to Destiny's end game content and have been a major part of military strategy since the revolutionary war. Set yourself up in a position to do the most damage to the enemy while exposing yourself to the least from the enemy. That being said, I wonder if this wasn't done as a fix but rather a need for memory on the venus system. The changes they made to the citadel in preparation for HOW are extreme. They may well have had to shrink a few existing playable areas to free up memory for the new ones. Just a speculation on my part.
