There are a lot of positions where a good rifleman can take good shots. Still this is not a game that has obvious (and obvious is usually a bad idea to take position) positions for snipers, like cranes in Battlefield 3.
This is a team game. flanking and other maneuvers are very effective on most maps, on some it is necessary to win the map.
Depending on what type of gameplay you want, you will like the classic mode or the upcoming changes to the relaxed realism mode.
Territory mode is not team deathmatch. It is the goal to capture objectives, not to kill the enemy team. If you take a objectice without firing a single shot that is a pretty good thing. Killing people who cover capture poiints or who are in them is just a tool to capture them.
This is still a team game. The objectives and maps are not designed that one player can defend or take objectives alone. You usually need more people to defend a objective or to attack and capture it. This is a team game.
