Cad vs. Tactician archetypes

[Lohengrin]

I'm wondering why the Cad doesn't get the skill point boost like the Tactician does. They both loose three feats.

Cad: medium armor proficiency, heavy armor proficiency, and tower shield proficiency.
Tactician: heavy armor proficiency, tower shield proficiency, and the bonus 1st level fighter feat.

The tactician seems to get the better deal, not to mention they also get better bonus feat selection(combat, teamwork and Skill focus) and a free new ability at 15th level(Battle Insight).

Everything else is replacing existing class abilities.

The bonus Fighter feat can be used to buy the tower shield proficiency, or to get something else. And so it's "worth more" than the tower shield proficiency in itself.
Also: archetypes are all different, that's the whole idea behind them. They're not balanced, they're not equal and they're not fair.

Yes, the bonus feat can be used to pick up any combat feat. Is a feat really worth 40 extra skill points?

The tactician can also choose skill focus or a teamwork feat as a bonus feat. I'm assuming that is also tied into losing the 1st level feat, since it doesn't replace any existing fighter class feature.

Archetypes may be different but, they are also balanced. They are balanced against other archtypes, classes, and other classes' archtypes.
