Spear vs Knights... am I missing something?

And to actually address the thread topic...

In my experience with GURPS broad areas of competence works better than narrow specialty.

This particularly applies at character creation. In a lot of campaigns (system even has rules for it!!) acquiring a skill takes time and a teacher then points. It is usually easier to increase a skill you actually already possess. Specialty can always be grown with earned cp.

If you find youself up against a specialist you can often find ways to move the engagement away from his area and into yours and the more areas of competence you possess the shorter the move.
