After putting your 12 AP into your prime stat (failure to do so is a loss of DCs), and after spending 2 more points on tier 1 skills which do nothing for your casting, to unlock tier 2 skills, you only have 10 AP left to work up to Master of (Spell School). Each rank requires 3 AP to max out, so you put 3 into Specialist, Augmentation, and Familiarity and...yea, you get to put 1 into Master of. You can put 2 into there if you only spend 2 into Familiarity, but you can never put 3 into that skill unless you give up main stat increases. So OK, to get Master of maxed, you clip 1 stat increase and pick up +2 DC in a single school at the expense of potentially 1 DC in all schools if your main stat is now an odd number. *You haven't taken any other ability in the entire tree!* No sigils, no tempest, no nullmagic anything. There aren't the APs for any of it, including spell penetration!
Perhaps consider making the Specialist, Augmentation, Familiarity, and Master of lines be a single selection that costs 2 AP for full benefit, retaining the same pre-requisites. You could then go all the way up the tree, at least. You'd still only have two points left over for spell pen and you still couldn't take any of the flavor skills (sigils, nullmagics, tempest, etc), but it would be a bit easier to check almost all of the required boxes. Recall, I can get full DC benefit including full penetration from Exalted Angel today and still have points left over to take a big AoE heal (divine wrath), wings, and a very nice debuff for some flavor. It would be nice if Magistar could provide offer a little bit of flavor for those at which the tree is targeted (DC casters).
