If a non spell caster wants lv 3 spells it's at least a 5 lv investment.

If a caster wants extra attack they can pick it up in the cheap with a subclass (a superior version with BS) or just casting a spell that grants it. Or just summon something that is equivalent to a semi optimized fighter without even eating into anything other than concentration.

If a non caster wants the big low level mitigation spells then they can grab a feat or multiclass to get 1-2 uses per day.

If a spell caster wants at least 19 AC, better saves, and doesn't want to delay progression it's a single level investment.

The budgets for features is very lopsided in favor towards casters cherry picking huge benefits with little cost where the flip side needs massive investments to get the same.
