In CoD they arn't really fights, more like "I saw you first now your dead". And if they do drag on for longer than a second it's more like playing the lottery. The lucky guy (usually with the better connection) wins. My .02
But that's where the reflexes come in. There's plenty of times where someone gets the drop on me, I spin around, and take them down with some well place shots. Usually because they figure "Oh he's facing the other way, and spray". Admittedly, the opposite has happened to me as well.
In CoD, being accurate is half the battle. The other half of the battle is being intelligent about where you go, how you go about getting there, and your capacity to pay attention to your surrounds WHILE accomplishing objectives. Sure, there's plenty of people that hunker down into a Sabotage match and pretend the bomb doesn't exist, they just shoot and shoot and shoot. These aren't good players. Good players kick ass, take names, AND plant the bomb, or better yet, guard a less skilled player while he plants the bomb. A big part of it is being able to discern in a split second if a movement on screen is a hostile. Most players look in one direction and just play it like a shooting gallery.
Most players get
stabbed in their inattentive
ass.
It encourages a sort of adrenaline fueled height of perception that allows a player to rapidly engage hostiles regardless of direction of attack, or instantly decide it running is the best decision, while capturing points. But, I digress. This is all an aside..
The real issue here is not the pros and cons of COD (because the cons outweigh the pros the vast majority of the time). The real issue here is gunplay in Brink.
I'm fine if my character is just ripped and can shoulder the kick of an LMG like nobody's business, but the LMG should still kick like an LMG. The recoil is suppressed, presumably by the mad pipes of the heavy soldier wielding it, but it shouldn't just pop back after every shot and spray with slightly increasing hit radius. It should feel like a real gun, with all the difficulties of handling a real gun's recoil,
just toned down. This way, it maintains a realistic chunkiness that lets everybody feel like the total mini-gun wielding badass they wish they were, while still having fun.
