Maybe it's done so for balance reasons but something I noticed while playing more melee lately is the amount of time being spent stopping and locked in camera for the buffs.
What I've noticed in group combat with my partner is that by the time I've buffed with my abilities and run into melee range most of the stuff is already dead to her ranged attacks. Being able to continue moving while using the Tethren and other pact abilities that do this may help alleviate that gap closing into range and lead to more flowing and fluid melee combat.
