I think the idea of making an assassination a drawn out animation, makes the idea of a one hit melee kill, more realistic.
Its great.
the problems are, 1) it takes so long to finish, that the victim has gotten his call out to his team mates in time for them to put grenades on his "X", so perhaps taking away the victims "X" sign after the kill would make the assassination more valuable. I would also suggest killing the victims microphone feed until respawn, but then players would just enter private chat pregame
2) what if I am standing behind an enemy, and I don't want to assassinate them? what if I would rather drop their sheilds with a melee and finish the kill with a head shot... because I feel the time spent in the assassination animation will eliminate my advantage over multiple players of the enemy team, since I have gotten behind their front line...
food for thought.
I play at the highest levels in match making, and strategical considerations are more important than visual entertainment for me at that level... does anyone else care about that?
