I see your point, Though wizards DO still gain bonus feats (Inscribe Rune at lvl 1, and a bonus metamagic every 5), as well as gaining new spell levels 1 earlier, and the ability to specialize (different from the Rune-magic specializing). Plus, the whole "Spontaneous metamagic = 1 full round casting" thing.
Im not inclined to do much for wizards, though that could be b/c of my inherent Sorc love.
In this case, though, Sorc fits the bill more than Wizard if you ask me... Casting specific, pre-memorized formula from a book doesn't seem very Patryn to me.
