Sniping is different from camping because sniping is using a precision rifle and scope to pin down enemies, unpin allies, and take down strategic targets requiring a high amount of skill. whereas camping requires only a gun with a high rpm or damage level and patience.
both snipers and campers are homos. i don't play video games so i can hide in a corner and then hope to find some sucker waiting around so i can head shot them. i like to run around blowing things up. it's just lame to sit back in a corner and wait for things to happen. real men mix it up, jump through levels and generally be awesome, not a bunch of camping / sniping losers
