Unless you are entering a tournament that designates a certain class of marker must be used, who cares?
If you enjoy playing semi, go for it. If you would rather play with a pump, cool.
Each type carries with it a different playing style and challenge, and it's up to you to decide which one you like best.
Playful jabs at another player's equipment are all in good fun, and are present at every level of the game. If you actually mean it, and consider someone a lesser player because of their equipment choices, you have your own problems, need to quit worrying about it, and just concentrate on having Fun.
Isn't that the whole point of playing?

My Fast likes to shoot people!

I agree, I go stock, no AT. We had fun at D-Day shooting stock.

We're the first tank/plane in the video (shot 8 cases that day)

I toyed with Chappy's new CCM S6 at PBC and oh, man. the AT on that baby has to give the sterlings a run for the money. CCM really stepped up on this one.

Im in agrement with you warpedx but take for example this actual event from my last blanding game...Viper F.E.A.R.

I was at the North blue base with "Duncan" who was doing the handing out of missions we were only two...I had my Sniper II no Auto-trigger...Four or Five red players one with a satchel charge ran into the base. I fired at the red demo player several times before I was hit at least seven or eight times by a idiot with a simi-auto... who had the audacity to say"How Many Does It Take"??? three or four times he said that... Because I was dead I was bound by honor to not say anything because dead me tale no tales...
But I thought to myself an answer to his question. "How Many Can You Shoot In One Second"!....

My point being "Honor" this IDOT and Id say it to his face.
Had no honor because I wasn't shooting at him but he didn't have enough honor to not hose me down...Now I don't know if I hit the demo guy because there were no ref's around and he didn't check him self...again if I had hit him would he have called him self out...again I say "HONOR"....I was hit and could not speak according to the rules....
