Actually, Arcane Fusion specifies sorcerer spells that you know.That entirely changes things. Strictly speaking, you don't actually know Maximized Magic Missile, just Magic Missile and Maximize, so it's incompatible. Miracle has no such limitation.
Nope, it doesn't change a thing. See, here's the thing about working in shady territory - the things you depend on don't have clear definitions. "Maximized Magic Missile" isn't a spell anywhere, therefore it's undefined in the rules - trying to argue a rules point using that as your basis is effectively dividing by zero. Does Miracle as written allow you to cast a metamagic spell? Possibly, but if it does, it's solely because "a spell with metamagic applied" is still by rules definition "a spell" - it is not because there's a spell somewhere called "Maximized Magic Missile" that Miracle allows you to cast.
Maximize Magic Missile is absolutely a spell. It has a different effect from magic missile, is cast by a spellcaster, and can be put into a wand or scroll.
Let me rephrase, since I was apparently unclear. Is Extended Persisted Bite of the Werebear a spell? Is it level 7 or bellow? If the answer to both is yes, then nothing else matters. Period.
But even putting that bit aside, the errata doesn't say that spells with metamagic are not legal targets (which is what it would have to do to support your claim) it just adjusts the effective level.
And arcane fusion is a different spell with clearly different text. Rulings on one don't apply to the other. Sorry, just because the effects are similar doesn't mean they're the same.
Think of it like a TCG. How many cards have very similar, but different, effects, and the minor difference in wording leads to a different ruling? I can think of several.
So, basically your argument falls down on every level.
No, yours does.
