personally i think its okay to have 1 or 2....especially if the team in question happens to be mostly big guys
lol. my team for example, we have guys who does deep flanking, ghost flanking, suppression, paint bait, pod monkey, and commanders. I dont call the ghost flankers snipers as they move MUCH faster than usual, and theyre also the ones who can disappear into the woods without using ghillie suits. (i have done that, but most times im a deep flanker/scout) and we operate in 2-player bricks based on the British Army tactics, which is pretty effective when you have alot of SP1s and a bunch of fast markers as well as pumpers. yes we have alot of firepower in our hands, but the thing is, nearly everyone on the team have 6-8 pods on them....so we dont exactly have "daggers" (i only carry 34 tubes of pbs for my nelspot, but i dont call myself a dagger, i just like to run this way, i have been known to carry much more than a pistol lol..) we also have a hammer who only has 10 pods in his backpack, (considered light by most hammer standards) so in reality, we dont do position crap. we do whats needed, where its needed, and everyone is more than capable of cover fire... broadsword, sabre, dagger, hammer, all those are just suggestions. what you call a broadsword on my team, we consider the back guys.
we have an average weight of 230 pounds...so yes we're all pretty big cept for a few who are much faster and smaller
