I feel that you're mistaken...Points in tplmodv13.tbm are earned by striking the torso/head. Shoulders if you hit them hard enough will count as points, as well as thighs, but anywhere else is worth 0 points. You can focus on striking quite well while grabbed. Just watch any of LesDuncan's videos on TPL. He explains it way better there, and there are actual matches between highly skilled players (i.e. Kolorz, Zero, Demo) who focused on striking in this mod while grabbing.
