Unfortunately Professors are the most complicated of the classes with their odd conditional skill trees. (If you have two of these and they have three of those, then... That's anything but straightforward.) But it helps to just focus on that section. All the rest is a nice to have to understand what's going on, but if you just remember your bit, you're doing pretty well.

What you really need to do is to know if your Proficiency Charm is maxed or not, because that's the thing that drives the other decisions. It's just not worth the 7 focus otherwise.

Ah, yeah, as I was telling her, that may be down to the latency. It's still early days, so there's hope it will improve.
