Totally agree about the snipers dream bit...think that's why many (but by far not all) users use it in their tank load out.
Heavy armor makes you move slow anyway, may as well have a big gun to go with it.
I tried tank bro, the most lethal counter for that playing style is a horde of opposing players rushing your base with Spas and Scars. Tanking definitely works well for devoted snipers who are not willing to rush/use pistol and melee at all, as well as Smawers to a degree, I agree with that.
However, there are ways to get around the whole mess of slowness with a carbonizer. Speed can be a carbonizer users strength.
