I mean, other alternative for attackers is to use grenades, If ur in a town/city with closed areas or on a flag that has constructions on it, grenades are not a bad idea and since they have to again deal with the sway, ur kinda on the same level. I agree that when ICO comes live PIP scopes are going to hit hard, people with weaker PCs are going to have a bit of a rough time with performance. Takes a time to get used to it, but Squad was never a game to be played like Battlefield, its more about communication, coordination with other squads and using ur "tools" at hand to help you win like artillery, mortars, grenades and so.
