First let me say that spawn killing is inexcusible, regardless of the weapon or tactics involved. The unforunate exeption is that now games like CoD use spawn points that move to the action (which is, according to developers, for the benefit of mainstream players, so nobody gets bored moving to the action) and there's no way I'm not going to shoot a guy who just popped up next to me while I was fighting just because he popped up next to me, otherwise I'm dead.
I don't see where you are able to make the distinction between someone who is close and incapable of defending himself in CQB, and those that are at range and incapable of defending themselves at range. Both are helpless players for their flaws within the mechanics of FPS gaming.
You can't limit the options in a game in the name of "fairness" simply because one group is incapable of dealing with certain situations without then taking the "fairness" out of it for another group that was capable of dealing with those same situations.
I use the exampe of football again. If one team has no success stopping the run, but the other team is a great run team you can't expect the run team to come out and just pass the ball in the name of fairness, particularly if they aren't any good at passing the ball.
Yes, you want the game to be fun and you need it to feel "fair" to you for it to be fun, but that doesn't mean that it will be fun or "fair" to somebody else.
And again, I'm not trying to argue that they need to change the way Brink is now, but I think people are seriously overestimating the gameplay changes that are currently in place. When the game hits stores and people are still able to snipe successfully there's going to be a push to change the mechanics even further.
At what point does that stop and how fair is it to people who buy the game, accepting what it is right now, and then get it changed out from under them into something they no longer can play.
EDIT: to the post above, the beauty of games is that we get multiple chances and I have never met a sniper that "always" wins.
First, I feel spawn killing is a design flaw, but it is completely "excusable" to exploit all design flaws available in a game until they are patched. The only methods I don't condone are ones which require outside manipulation (modded controllers/weapons or router manipulation) or ones which only some players have access to (host advantage or character-specific glitches). But if an enemy spawns in my line of fire, I am going to kill them. What should I do, wait until the enemy sees me and raises their sights before firing? Count to "5" before attacking? No, if I have an advantage, I'm going to press it. Any issues that need addressing should have been taken care of while the game was in development.
Second, Brink needs to distinguish itself from its competitors. I think it's been successful in doing that so far (although they need to ramp up the advertising a bit). In addition to the visual style and SMART system, which are just cosmetic features, it needs to prove its gameplay is different. What better way than by saying, "We're not just for the hardcoe gamer"? I can't tell you how many times I played a Halo game or Battlefield: Bad Company 2 and said, "This game would be great if it weren't for the snipers and vehicles." I'm sick of getting into a firefight and having a random person kill me from a mile away.
Case in point: last night, while playing BFBC2, I was upstairs in a house. 2 opponents had me cornered and charged up a staircase after me. A quick close-range battle erupted, and there was about 7 or 8 seconds of us jumping around, shooting shotguns and slashing knives while juking and backpedalling. When the dust cleared, I was alive. And then I died. And as I said, "What the [censored]?" my deathcam showed a sniper across the map reloading. And this happened several times--I'd have someone dead to rights and a helicopter would kill me from 5 blocks away, or a sniper would finish me off after I killed his weakened teammates, or I'd sneak my way into a base and get picked off by someone who wasn't even near me.
I think Brink will change that, and that the game will have more of a measure of skill than people believe. When two level 20 characters fight, it's going to be a test of skill--who has the better build, who is the faster player, who has better aim, etc.. But then, when the battle's over, the winner won't get killed from a mile away. Instead, they'll heal up and press on. To me, that's FAR more attractive than having the ability to headshot someone that doesn't even know where I am.
