I rarely do Frostfire. When I do, it is for the badge. I am almost always on an exemplared toon, sometimes one custom designed for content in that level range if I am seriously badging. Basically, it is always lulz for me.
I know many do FrostFire as a "mini farm" or a "walk down memory lane" or a ritual with any new toon. I almost always approach it with the attitude that we will clear everything. That team wants experience and to savor the moment. Sometimes the leader even bumps the level, which makes the first floor or two challenging. Just grind and clean. Everything. By the time you get to FF you are cakewalking the baby home.
