I disagree. An AI without a strategic focus is a lost AI. It will not know what to do. If faced with Fraction A fielding archers. Fraction B fielding spear untis and Fraction C pursuing a diplomatic strategy its research results will be minimal as it bounces back and forth researching a little in one area and a little in another area as its threatended by each fraction in turn.
Is it better to have an army that does everything in moderation or an army that excels in one area?
Example: I played a V1.39 where I put every Sovereign Stat point into Intelligence - that game me a sovereign with 45 points in Intelligence - enough for spell blast that does 15 points of damage AOE or Arcane Arrow 22 points of damage. That's an example of focus. I could have placed those points into Strength and achieved one heavy hitting damage dealing sovereign. If I had split the pointsbetween strength and intelligence the results would be much less effective and a leader that does not excel in one area.
I do agree that the AI needs to adapt to what their enemy does; however, it also needs a strategic focus. IMO the current AI is weak because it lacks this focus.
I agree that the AI needs to better counter the opponent's strategy. I never see the AI casting Wind Shield or Spell Immunity when faced by an archer army or my spell casting sovereign. If the AI is taking a melee focused approach the AI should research wind shield to protect his units from archers. If the AI is taking an archer approach he might be best served by researching spells that slow down attacking units (or cause them to lose their turn).
