That really depends on implementation details, like how long you have to hold the button for while behind the other player. For example, imagine you have to hold the button down for an amount of time while behind the enemy, you wouldn't be able to simply jump over him while holding the button.
it'll just add some unnecessary animation that'll slow things down and take the player out of their normal perspective for about a brief period of time
Whether it is an "unnecessary animation that'll slow things down" is really more a question of a different type of gameplay. Clearly Bungie decided to persue this for a reason. Sure there's the "that was cool" factor, but also there are gameplay reasons.
I'm guessing you'll be vulnerable while the animation is playing, so there's more of a risk/reward for performing the assassination rather than shooting the player in the back.
If brings up questions like: can you complete these animations while both of you are in midair? Do you have to be on the same plane for the animation to trigger or will your player warp to where the animation normally begins? At what point during the animation will the "boarded" player actually die? Can they be interrupted if the assassinating or assassinated player dies mid animation and how fluidly will that animation play out afterward?
Good questions. Can't wait to find out the answers.
Point is I don't see what this animation is adding to the game and what was so wrong about the old system of assassinations without animations.
Simple answer - more risk for performing an assassination, but extra kudos for getting it done, depending on how hard or long it takes to execute, and old assassinations looked silly since you're basically just knocking someone in the back with your gun? My guess is that the developers sat down and started a discussion about increasing the time it takes to perform an assassination, and then someone said that they should have a special assassination animation rather than the default melee attack, and it went from there.
Personally, it's the least of my concerns about Reach - I use assassinations maybe once or twice a match in multiplayer, and think that a brief animation won't cause any problems for most people.
