Thank you.
In general, I'd like to see unit statistics play a much larger role with standard troops (as opposed to merely heroes or sovereigns), because these statistics will also be used in other forms of interaction, such as resistance to magic or other certain effects (suggestion: agility to resist things like spider webs or traps).
One could also imagine improved versions of certain abilities, such as Riposte in my quick example above. I mean this: Units may be trained with additional Abilities (for a price, particularly in troop training time -- I see this as the most important resource), but only if those units meet the statistics requirement (whereby we can imagine that for many mundane Abilities, this requirement is a default 10). But some Abilities improve if the troops in question have improved Statistics (be this temporary, due to a spell or other circumstance, or permanent, due to training).
Example 2: Shield Wall. Prerequisites: Unit must have a Shield equipped; Unit must have 9 Dexterity and 9 Strength. When this Ability is activated, the Unit gains -5 to its attacks and +7 to both dodge and defense. For each point of Dexterity above 10, the unit gains an additional point of defense.
Note that a unit which was Weakened (I envision a spell or effect of similar name) would not be able to activate its shield wall if its Strength fell below 9. An elite unit which has mastered this ability and has also a high Dexterity will benefit even more so, as it would from being near a caster who can cast inexpensive Dexterity buff spells.
Example 3: Embolden. Prerequisites: Unit must have a Banner equipped; Unit must have a Charisma of 11 or higher. When this ability is active, all units on the tactical battlefield in a radius of 1 tile around this unit have their accuracy rating increased by 2 and an additional 3% chance to resist all hostile Enchantment spells for each point of Charisma above 10; for each 2 points of Charisma above 11, the radius of the Embolden effect is increased by 1 and all units affected by it receive an additional 1 point of defense and 1 point of attack.
Note that training this ability might be excellent for both heroes or sovereigns as well as particular specialized task-forces or support units such as a Paladin (or whatever). A Banner is an equippable and relatively inexpensive single-handed item (which looks like a flag with your nation's symbol on a pole); another option would be making increasingly expensive Banners which give boni to this and/or other Abilities, special ones giving boni to the bearer's Charisma as well. Downside: one hand slot is filled. Note that Charisma buffs would be very effective for a unit using this Ability. If this Ability were good enough, it would give an incentive for training at least some troops who will be also trained to use it with increased Charisma. Note also that if this ability were strong enough, it might also make researching and casting Charisma-debuffs a feasible option in late game. (Just an idea to get some of the less ostentatious Statistics get some raison d'etre.)
I have buckets of examples such as these in stock.
