It just won't work
Why won't it work? Will the servers crash? Will the game explode? Will there be no winner? Or are people just stupid and have weak game and cry like babies (this is happening already, thats why you get clown makeup and stickers)???
I cant imagine anyone wanting to play this.
It would require minimal skill and GREATLY encourage camping in the mode. There's nothing worse then getting picked off by a LMG with a 4x scope because its a one shot kill.
I hate the mode all together tbh. I don't think someone should be rewarded if they hit me in the foot a milli second before I was going to hit the chest/head. However I realize there is a portion of the community who plays this mode.
But yeah, a HC Blackout would basically be complete luck based on the circle drop. You'd have zero chance of moving across the map successfuly so the winner of each round would be the guy who landed in the circle and never had to move.
I don't know who has to empty an entire clip into someone to kill them... I find I'm making kills with 5-6 good AR shots. I have no issue picking up Sniper headshot kills in one shot either.
