Ok ponder this fal.
You have a 5 agi and say 5 dodge, with a spec in melee dodge. You roll 5+5+5+2 on full defensive.
With the pistol as club spec you can eek out 2 more dice 5 agi+5dodge+5club+2dodge spec+2club spec. And even with the +1 to dodge from the MA advantages its more dice to block it than simply dodge. You could save yourself 10bp, or 20 karma and just take the bonus to firing in melee to negate the minus you normally get and screw the extra dodge, since you now have a larger pool my way anyhow.
Right. Or you can take no Clubs skill at all, because Firefight gives you bonuses to shooting at point blank range, so instead of ever clubbing people with your guns, you use your guns to shoot them. You use Dodge for defense (both in melee and at range), Pistols for offense (both close and at range), and
don't need the extra Clubs skill for anything, or a decent Strength score to go with it (which then frees you up to be that much better at Agility, Reaction, or whatever else). Both builds are valid. Neither one is "right" or "wrong," it all comes down to what a given character wants to focus on.
In a perfect world, sure, anyone who's supposed to be fighting in melee would have the whole Close Combat Group -- because, for instance, no one ever
just teaches you knife fighting, you'll get a little grappling in there, some kicks, some elbows, and everything you learn to do with a blade you probably practice with something else -- but that's in a perfect world. In Shadowrun, with the abstraction of the melee combat rules, that just doesn't happen. It doesn't matter in the real world that Filipino and Japanese martial artists (just using Kali and Kendo/Kenjutsu as examples, off the top of my head) have been using sticks to practice their sword/knife/machete work for years and years, the two skills are
completely different in Shadowrun's reality.
And accepting Shadowrun's reality is an important part of looking at, and designing, a workable character. In actual character creation, folks are scraping by for points, and sometimes it's just plain not worth it to try and shoehorn in Unarmed, Clubs, and the kitchen sink when your character's main theme is "gunfighter."
