you will always play as an attacker or defender depending on the mission - you can choose to play through these in the campaign (story mode) in standard matches (no stroy attached) and I know stopwatch mode is in (the same objective gameplay, just whatever time it takes for a team to win, the next match the other team has that much time to beat it)
they did this to focus on the team element - if you put one-hit kill snipers in, you're going to have everyone hiding trying to bang out headshots - if you make snipers less effective, you have less people sniping.
to give you an idea of how low health is for Lights - without a health buff, a knife can one-hit kill a light.
But without details, we don't really know how significant that is. If a knife can one-hit a Light, and leave a medium with 1% health, then it's not such a big deal. Also, if a Light's health is so low, he must be REALLY ****** fast.
