Yup, pulse grenades are best as area denial. In salvage and especially control, they work well. If your alone, throw a pulse grenade in the middle of a control point and you just gained a few seconds for your team to get into position and back you up. Playing Clash? Throw a pulse grenade right on the door frame. Stops enemies from rushing through or following up for a kill. This let's your team to either flank or get into a better firing position.
