Wait, what? Where does the Mental Limit come from when Spellcasting? That's not how it works. And why are Reagents and Edge not mentioned? And the Summoning page doesn't even mention the Force as Limit, Ranged Combat doesn't mention Accuracy as Limit and it's still stuck in SR4's modDamage>modArmor instead of modDamage>=modArmor, Defense doesn't mention that you can still use Full Defense in melee and that it can stack with the other 3 defense options. I don't know enough about some of the other subjects to be able to see whether the thing is correct, but it has some big flaws in it that seem to come from misunderstandings and SR4-rules stuck in their head.
