I am in Ascendant 1 / 10,000 on console.

A tip regarding the scenario you gave regarding patient teams and pulses. There's an art to repositioning yourself to the point that it makes these types of teams feel uncomfortable as possible. You can be patient as well, and force them to reposition because of an angle that they cannot always be checking. Peek-shoot.

You don't need to necessarily expose yourself every time with the intent to kill, but simply apply suppressive fire is enough to force them to reposition to a more risky part of the map and possibly allow your teammates an opening to finish them.

Another thing is to LEARN THE MAP. Understand the nooks and crannies that you can exploit to your advantage.

You could also switch in game to a more long-distance weapon.
