On the subject of min/maxing, see my thoughts:
On the subject of WFRP3 and spears: I like the "breakage" rule as well. I generally like to include the concept of weapon breakage or degradation in my games.
Also regarding spears, I just recently watched the fun martial arts film "Wing Chun" again. The fight sequence at the finale of the movie is an excellent illustration of why a spear is not an optimal weapon for all circumstances. Spear-fighting indoors is a very awkward experience!
