Then the question is this: Why do Mages require an entire tier of talents revolving around mana regeneration when only 1 spec cares about mana regeneration, and is designed so the passive regeneration provided by Rune of Power will always be the superior choice?

Myth. Arcane's slated playstyle heavily favors Rune of Power for its consistent passive mana return as opposed to DPS interruptions and subsequent loss of passive regen through Invocation or the utter failure of a talent that is Incanter's Ward.
Honestly at this point I'm starting to think Rune of Power could just be made baseline for Arcane.

No, it should; Mana is Arcane's resource, equivalent to Energy, Focus, Holy Power, Soul Shards, etc.
There is no issue with Arcane relying on management of the blue bar to maximize DPS. The issue is when baseline talents and abilities are designed with it in mind that impact Fire and Frost.
