I see these guys a lot. Every game at least one gets built by someone, but more often then not they get run over, shot to death, ambushed by a Bren, countersniped by a recon Tommy (heh heh ) or mortared. Sometimes, I'm just moving around and I run into a cloaked sniper then "wtfpwn" lol. This happens pretty often.
This leads me to the conclusion, for 340MP and the amount of support and micro it takes is the sniper overrated? I would say its the punk kid in us that finds the sniper so "cool" that makes use a unit that isn't.. very good.
I seen some games where a sniper in hands of a skilled player backing up with a HMG can do some real damage but out of the 120ish games I've played so far only 2-3 were the sniper significant and got off more than 2-4 shots.
