NECRO-DOUBLE POST YEEEAAAAHHHHHH!!!!!!!
Ya know what else makes me salty? Game breaking gamers.
Yeah, it's true, games are just too complex these days to be even close to perfect. There will always be exploits, and always a more efficient gaming style that is very different, or even the exact opposite, of what the developers intended. For example of such game-winning playstyles, Assassin's Creed; both Brotherhood, and Revelations.
The game mode Manhunt intends for you to stealthily sneak about to get kills when you're on the offense, and for you and your team mates to hide together on the defense. Not only is there strength in numbers, you also get rewarded with quite a few extra points when hiding the more of your team mates that are hiding close by.
However, the best way to score high when on the defense is to literally rush at the team on the offense, and attempt to "stun" the shit out of them (stunning the enemy on the offense gets you a lot of points and possible bonus points as well). Thanks to the death streak perk "Boost Cooldowns", you get your two abilities of choice back as soon as you respawn after death for the entire match afterwards. Two stuns alone often easily scores higher than a single kill from the opponent; when done with basic skill, these two abilities will get you at least two stuns each every time you respawn. When done flawlessly, you'll get four stuns, and then run away without even being killed. Two stuns is almost always worth more than an enemy's kill. Any more and it definitely is. So basically, Boost Cooldowns is not only a broken perk, but also allows you to play the game in a way that should NOT exist.
If your entire team is behind you with this bullshit "best defense is a good offense" strategy, you can lock your opponents into a never-ending chain of stuns. They will get one poor, low scoring kill per every two or even three stuns your team gets. The person on the defense who dies attempting to stun everyone rushes back over to the mosh pit of stuns, and replaces the next person to die endlessly until the round is over.
... Yeah, I don't think the developers intended the game to work like that. This exists in both Brotherhood and Revelations; they tried fixing it when developing Revelations' multiplayer, but to no avail. People still got around the safe guard to prevent infinite stuns.
Gamers who play with strategies like these; solely to win, at the expense of everyone else's fun and even their own; make me salty. It's just not as fun as playing normally.
