Overall BE lists and points costs are pretty good ... with only a minor few anomalies. The complexity is such that this is a hard system to mini-max and therefore it makes for a much better game whereby no single type of army or troop type overly dominates !! BE is VERY balanced notwithstanding some minor wrinkles.
Anyhows, in my dim dark past I was a system architect and programmer, so I used to get paid for finding/eliminating system loopholes. It's been a dreadful bad habit that has dogged my whole life ever since

So ... I've been messing around with the 'edges' of BE points system as that plays out in army and troop types choices when compared to on-table effectiveness.
In a wargame list building sense, usually that means having a look at what one extreme or another might generate in game impact terms. For example, you might try and have an army consisting entirely of the lowest priced troops which will test whether the tradeoff between quantity and quality is 'worth' the difference in points costs vs the game-impact. Or vice versa.
This particular post is focused at an army list level, but I might put up a few ramblings about some of the individual troop types in due course.
Here is a 200 point list that is incredibly difficult to beat on-table. It may be that Guards status or higher Morale level (5 or 6) points costs need to be increased.
Anyways, feel free to give list a try out. Sure, it is small; but it is a nasty combo especially when taking morale tests and reacting ! Don't take my word for it, give it a try
