Yes, I'll update it today. The minimum requirements are at the bottom of the article.

Good question. For Subordinate City Mayors it applies because they are commanding troops during battles (as long as they have troops remaining in their respective Subordinate City). But, the offensive Buffs only apply to the troops within that particular Subordinate City. On the other hand, their Debuffs apply to entire enemy army. Since Duty Officers and Senate Generals (another form of Duty Officers) do NOT command any troops during battles, none of the "when general is leading the army" skills apply to them.

I believe the community's general thinking is that IF the top tier of Mounted is NOT fully killed in the first turn of attacking (3rd turn of battle), that all Range tiers would attack the same layer again on their next turn.

Focus on Debuffing the enemy army. Attack, HP & Defense only apply to the troops within that particular sub-city, while Debuffs apply to the entire enemy army.

Yes, I've bitten off more than I can chew in the past 6 months, so those articles are out of date. I've gotten numerous requests to update them, so it's high on my to-do list. I'm trying to get back to updating them "soon". Maybe next month? But, I've been saying that for the past 4 months, so don't hold your breath.

Mostly money... Flexible Specialties are pay only right now. I'm assuming you've figured that part out, and gotten a Precision Arrows Flexible Specialty, then gotten it to level 20. Now you need another one, or two or three (11.1% chance at $100 US per chance), and will need to "Disassemble" it/them to get the pieces required to take it to the next level.
