Will + Will is also a bad design, if only because it's just better than using two attributes. Willpower is already a pretty great attribute. Logic is rarely that useful for non-hackers, so especially compared to that, being able to focus on just Willpower is strong. Especially when you consider that "Hey, using Increase Attribute [Willpower] means I get twice the bonus to my drain pool!" I regularly make spellcasters with 4 Will just so I can get a F4 Sustaining Focus or R4 Focused Concentration and always sustain that spell, because 8 Will is great, and so is +4 drain. But a Romani Dwarf taking the -2 to sustain a F7 Increase Attribute spell to give themselves 11 Will and 22 Drain Resist out the door is frightening. And that's before you even consider the Quickening metamagic.
Aspected Magicians got a lot of love in Forbidden Arcana, one of the few things I can say I like. Dedicated Spellcaster (or whatever it's called) is great, though while it "fixes" the lack of spells aspected magicians get in chargen, it shouldn't be required for the archetype to work. Unfortunately, Dedicated Conjurer is not really strong, it just breaks lore by granting access to more spirit types, which I dislike, and even though they gave Enchanter its own priority, they still didn't give it any preparations to start with so I'm pretty sure it's reasonable for me to say "fuck you" to that one. The one thing people complained about and everybody knew was annoying since the CRB came out, and they set themselves a place to fix it, and then just didn't.
