Because it's an objective based game. Killing people doesn't matter in Brink. Also, quit trying to relate this to Call of Duty. Call of Duty is trash and has a learning curve steeper than Mt. Rushmore, and the fact that everybody here always bashes that game even when I'm directly using Halo as my example is annoying and frankly pisses me off. Brink still looks like it takes 5-6 shots to kill with the exact same weapons that are in CoD, so in essence it has the same play style as CoD, but with longer health bars. Say whatever you want, nothing is gonna change that.
And no, I wasn't saying the tactics don't apply unless it's TDM, you pulled that out of thin air. I was saying TDM isn't a mindless fragfest after you claimed it was. Sure, there are ways you can use basic teamwork in Brink, but nothing that's as revolutionary that would make Brink more played competitively like you claim. Whether you like it or not, Team Deathmatch is the most popular game mode in any shooter and a game that relies purely on objective based gameplay is going to alienate the majority of people who compete in clans. The closest the average person has gone to an objective based game in a clan war is Capture the Flag. And don't give me more of your bull "Call of Duty CTF doesn't even rely on having your team covering you" BECAUSE I DO NOT CARE ABOUT FREAKIN CALL OF DUTY!

Its funny how you downplay the importance of bullet damage in shooters and say its just like CoD but with less bullet damage. Bullet damage is a very important thing in a shooter because the lower the bullet damage usually take much more skill to play (Killzone2, Halo, MAG). So yeah, the gun play can be exactly like CoD but have low bullet damage and that alone makes the gun play better.
I fail to see what TDM being the most popular game mode have to do with it being required for competitive clan battles. So what most clans would be alienated by lack of TDM, so would most players in general, this game is not for casual gamers in case you haven't noticed.
Killing does matter in objective-based games, how else are you going to take the objectives? The enemy isn't just going to hand the objectives to you.
