We already have head-shot and wall-bang indicators in the killfeed, why not go the extra mile and add in no-scope and smoke-kill ones as well like CS:GO? I think it'd be a great, non-game changing addition to the game, just to have proof when you or an enemy do something nutty. Maybe they could even add some in for running or in-air shots as well. Anyways, just a thought! :)
