No, you guys simply are not listening. The blaster can be used but not for the person chasing. If you have 1 person stationary and a few chainwhores thats really all you need. Lead with the speedpack and the blaster, your sure to hit the capper at least 2-3 times, lower his health then get some CG chasers.
Like I said it's a team effort and the best way to take one down is a COMBINATION of tactics and teamwork. Look at it this way-
We have 2 chasers with the chaingun
and 1 guy with the sniper rifle.
The sniper stays completely stationary, and then uses the speedpack & the blaster as the capper comes midrange. The blaster is a decent weapon IF you can learn to lead at midrange. Then you have the sniper simply alternate between the rifle and the blaster the entire time.
You have 2 chasers with the chaingun and grenade launcher. These people will be pressuring the grappler to move, also they sometimes force the grappler to move in predictable ways for the sniper to take them down. Also I'd like to point out that considering an aimbot can eliminate a grappler within 2-3 seconds with the CG, it shouldn't be "omg so effing impossible" to take them out without the aid of an aimbot. You just have to be good at it.
JonnyFong, I'd kinda like to point out that I am sort of a grappler myself, I do crazy loops, grapple on the side of hills, and switch direction at the drop of a dime without losing much speed. Any DECENT CG'er can take me down, like I said all it takes is practice.
Last thing is, they don't have Godmode on or unlimited ammo. If your HO rapes the base, and you get enough pressure on them they'll have to get more ammo from somewhere. Like I said TEAMWORK & SKILL are all you need to counter this "effective" tactic.
