I don't think you die too quickly, I think that not all bullets that hit you register until the last couple making it seem like you die right away. I've noticed this in close contact but I've managed to outrun being killed out in the open from range by running to cover, if anything I think that's more realistic as bullets would lose velocity over distance but would cause maximum damage close up.
As for snipers on roofs, the XM25 Airburst takes care of those! And the SRAW to a lesser extent.
Hmm. I dunno. I still don't really like the game, it doesn't suit the way I like to play. I'm going to have a couple of weeks away from it (been playing Dues Ex which is pretty awesome and my AC4 arrived today as well ) maybe when I come back to it I will find it a bit more fun.
Edit: and I don't even know what an XM25 Airburst is.
