Unarmed Suggestion
From zero to 100 - I'm so excited about the upcoming Fallen Enchantress; I've been out of the turn-based strategy gaming for a long time (after playing MoM non-stop for years). I've been looking at the many developer posts and the little bits of information that have been showcased on FE and I really am very excited.
There's something I would like to see supported in the game; even if it is a sub-optimal option: the ability to effectively field units without armor or/and weapons. It's something that has fueled my imagination for a while - to have a squad of elite warrior monks. I don't know what mechanism would best tie-in such an option into the game - but from my searching the available information the tech-trees suggest themselves, as weapons and armor are handled in those terms already. From a balance perspective I'd imagine it needs to be classed as sub-par; but with the potential to become effective through an on-going tech option that can be researched continuously.
Alternatively, maybe a set of traits could fill in the same function?
Strategically there might be some value in such unarmed units - low reliance on (metal) resources; and possibly the lack of high attack/damage could be balanced against higher combat speed or spell resistance.
