Specialization will take care of itself in the future. The cap will not remain at 50. It will increase as the game progresses. With the current rate of progression <98K to 49> crafters will have to concentrate on one specialty just to keep up. Leveling other crafts will only be done in order to satisfy sub requirements for the main craft. The current system allows player to build a solid foundation for those subcrafts. The one thing I do not want to see is the system already in place in FFXI that forces you to remain in one craft til completion. This limits a p[layers ability to adjust to changing game and economic conditions.
