The laser is the most skill based player fragging tool in the Fire Support arsenal and can be called twice as often as an airstrike can. She’s also good for fighting lower skill players as you can be placed faster and take advantage of green aim.
As far as high level play goes…sadly the meatier mercs are better when you’re probably going to get hit regardless.
Rule #1 about the laser though: you only need to see where the laser needs to go, not what’s in between.
