So I don't know if anybody has noticed but if you get more then 6 knife kills in the first minute of the game, you do not get a reward. By the way, i am not sure but i think if you get 5 knife kills, it says you got 2 but gives you 600 points, but that isn't the main problem. I think that should be updated, since this issue has been here ever since this challenge was implemented. Also i think that when you get the spy plane for 5 kills or the sr71 for 10 kills, they wouldn't be instantly activated, but instead given as a killstreak reward. When you get 6 kills you are given a ballistic bowie knife, but no points, and i think you should be given some points as well. Also i was thinking, when you get about 20 or more knife kills you would get a ghille suit, witch protects you from sr71 because that is mainly the thing from witch you die as a knifer (The same effect could also be applied to the scout class ghille suit).
The bowie ballistic knife and the sickle ballistic knife has glitchy textures, when the knives are almost off the screen they sligthley teleport and that really bothers me, maybe that could also be fixed?
But i went a bit off topic. I would like to see some more rewards for knifing in the first minute.
