Using Units: Part 1

This is great, and I will have to go over it a few times, as this is one thing that I still struggle with. About Fennblades, though- I've always seen them called a jamming unit, and they seem to fit that category better even by the terms defined here. So Kriel Warriors are a tarpit unit and Fenns are a jamming unit, or am I missing something?

As for another type, I can think of one, and that is support units. Krielstone, Choir, Paingivers, mechanics of all sorts.

Seconded.

This is a case of learning styles, and given the tone I'd say this is also a case of believing everyone thinks the same way you do. 

Personally I have extreme issues remembering things in general, my memory is very poor and trying to bring up specific information with no linking context becomes nearly impossible. Were I learning the game or in my first year or so and had someone just regaling me with information about precise 2" melee placements for frontal screening, or other similar concepts which are very specific, used on a case by case basis, and gives me no physical context to the situation, I will lose track of that information entirely. The way I've found over my lifetime that I'm able to most easily bring information to the forefront of my mind is through categorization, titling, and use of context rather than a specific "if X do Y" kind of format. 

This depends also on your target audience. For example, *now* if I was given that kind of ultra-specific information, I would be able to use it just fine because of the years I've put into the game and the practice I've had internalizing and using information once I hit the tabletop. Were this guide targeted at veteran players, certainly, I'd suggest that as well. When you're talking to a more broad spectrum of people, though, this form of categorization and organization makes it simple for the mind to comprehend and causes it to take up less of your time and energy thinking through in a game that can already be quite overwhelming as far as choices and input. Further, you're creating a framework from which a player can grow on their own experience; a guiding hand down the path rather than just picking them up and setting them where they need to be, as it were. We may, in time, drop an 'advanced' guide with more detailed and specific things for people, but something like this gives the most room for internalization and growth rather than being directed only to the end result. 

Also, as just a person... I'd suggest being more open to the concepts being presented you when dealing with teaching styles. Educators are important, but I realized very early that many were far too unwilling to accept the learning styles of different students and has lead to one of the biggest weaknesses of our education system; the complete rigidity of how its students are required to learn regardless of whether or not that style is any good for them. My experience in the school system all the way from Elementary up through Universities lead me to a very cynical, angry, and resentful view of how students are handled and how schools go about their craft. Now as a parent, touring schools for my own child getting ready to enter the education system, my number one concern from each place we go to is the same: is this school capable of being fluid and flexible when it comes to teaching to students with learning styles differing from one another. 

I agree with the way they are doing this and I am very much in that target audience. There are dozens upon dozens of different units in this game. That would be completely unmanageable if they all did wildly different things. FWIW, I do recall them saying that one unit could occupy multiple categories.

As for categories, would skirmishers qualify as a different one from ranged units? Striders are a prime example. Trollkin Scouts would be if they were playable. :P Would Battle Bears count? Without Reposition or something like that, they don't hit and run, but they do harass flanks in their own way.
