For the spell Battlemind Link it states that the two participants in the spell gain their simultaneous die rollings if they both make a melee attack on a target or both make a ranged attack on a target. What is required for them to both be making a melee attack? Do they have to hold their actions and swing simultaneously, both be threatening the same target with both declared they're going to swing in melee for their actions that round, or simply both have declared melee/ranged attacks will be their actions on that round for that target?
