Spell Penetration doesn't affect everyone, and doesn't increase the power of the spell.
All Metamagic feats in the core rules add to the spell level
All Item Creation feats require XP and GP expenditure (why the hell aren't they just skills?
What's left... Weapon Focus? That's about it, really.
So yeah, of course they're gonna take Spell Focus BECAUSE THERE IS NOTHING ELSE TO TAKE
I agree with this. Especially for a wizard, who can get some of his metamagics and item creation as bonus feats, there aren't a lot of good choices for low level mages. Spell focus is just one of the only good ones. Probably may favorite one is extra slot from tomb and blood, at least that's something my wizard can use often.
