That's a pretty ingenious way to use flares, but I have to say I was a bit disappointed after watching your video. When I saw your thread I thought that I might have overlooked the throwing skill, meaning there was a new way for me to play the game. If anything, it just proved to me that throwing is even more useless than I thought, considering the lengths you have to go to make it effective.

Lenghts? All you need to do is to pick perks accordingly (same as everyone else) & gather enough flares - it's not like every other character gets his weapons for free. That's it.
