Glad to read that you are happy with the changes!
I’m not sure where I stand as my UE book hasn’t been delivered yet, so my information is all 2nd-hand.
That said, mybrotherhood army (yes, I know, this army has been linked before. Here’s it again). was pretty feasible in 2nd edition and maybe not so much in 3rd edition due to an over-reliance on cavalry and monsters.
The main reaon why Brotherhood apealed to former Bretty players was due to the variety of cavalry that could be fielded. The 2nd ed. Brotherhood army had light cavalry, flying cavalry and 4 kinds of knights, ranging from the mediocre initiates to the superb order of redemption.
In the new edition it’s either light cavalry OR flying cavalry (depending on green lady or brothermark) and 2 kinds of knights. (paladin knights/abyssal hunt or order of the brotherhood/redemption). This consolidation, (or lack of variety as it’s also called) takes some time to getting used to. The real question is: what’s Brothermark’s unique playstyle compared to -say- Basilea, Rhordia or Kingdoms of Men.
As I don’t have the book I cannot answer this question at this moment. I doubt that I could answer the question without playing a few games anyhow. As I am trying my army as basilea for the time being, Brotherhood will have to wait a few months.
Maybe other Brotherhood players can answer this?
