Problems still present (details in first post):
>>> The strategy cards that increase revenue are described so that the bonus seems bigger than it is. <<<
I consider this a highly unnecessary flaw. Slight impact. People will learn. Best correct it before people learn that "increase by 200%" means double and not triple.
Master dragon research "permanent" effect
The wording is complex and not entirely clear. Most people, myself inclusive, will understand, though.
Cheaper strategic purchase card
Says "all" air/naval/ground units will be cheaper, but affects only the country it is played in. Wording could be better.
Manual: Contradiction in hunter description
Minor error on weakness list. (Should be corrected.)
Manual: Complex "Strong against"-entry for Imp Fighter
Manual entry might be worth redesigning. Change in design could benefit other units whose strenghts and weakness change with upgrades.
Trivialities and practicalities
A tiny addition (probably not something you'll bother to change): "Combat round" is synonymous with "battle", right? Battle might be a better term.
I haven't accidentally pressed "retreat" while intending to "ready" in a while. I still see a minor reduction in mishaps from rewording "retreat" to the more distinct "withdraw", or by rewording "ready" to "fight".
