In a Tome of Battle/Oriental Adventures game I'm playing in, two of us use reach weapons. There is an NPC Ranger archer that does not yet have precise shot, so the definition of "in melee" is important.
Say the BBEG is being flanked by myself and my partymate; we both have reach weapons, and the BBEG does not threaten either of us. The NPC archer is standing off to the side, so there are no issues with cover.
Does the archer take the -4 penalty for his target being "in melee?"
Would the answer be different if the BBEG also had a reach weapon, or if the BBEG was a Troll, or some other creature with natural reach, and threatened both of us pole-arm wielders?
