I hate stupid "perks" like this...all it does is add randomness to the game. Why should you be able to throw farther grenades than me....because you played more? retarded shyt. Simple shyt like shooting mechanics, grenades, melees and movement should not be affected by perks...once you can give players perks to tweak these things to their liking the game becomes a fukk fest and balance is thrown out the window. It's why I don't fukk with COD, it's why Halo 4 pissed me off so much....i hate it. It's fine for single player, but once you crossover to multiplayer and I can only throw my grenades 25 feet while you can cover 50 because you're a rank 8 with better perks....bye bye balance. I hate the EXP system and what it's done to shooters.
