When I first got my pump I used to say things like, man if I'd of had my 98C I would have been able to take such and such a guy out. But then I realized that if I would have had my semi there is no way I would have gotten to that position. If you guys really like following the profile of Daggers they do crawl and play the stealth game. Crawling around with a gun with a large hopper and heavy tank would make how I play so much more difficult.
My set up is infinitely lighter than it would be if I had a semi. A lot of people are probably thinking, "Hey, this guy needs to visit a gym," and I used to think that too. But thats not it, just because you have Rambo muscles doesn't mean that having a lighter set up won't help you.
Sure maybe pump play didn't work for you, it doesn't work for a lot of people thats why its not as popular as semis. But sometime it just clicks for you and you do a lot better than if you had a semi. Pump isn't a fad, fads come and go, but I think pump play is here to stay, at least for me anyway.
I think its possible to do individually better SOMETIMES with a pump however you lose many team aspects of the game. Such as giving cover fire or distracting an enemy. Also as far as moving up goes BPS can do wonders.
