OK, some short and concise points here:

1. Siege AI.
- AI units should abandon destroyed siege equipment and do something other than getting destroyed by castle defences.
- AI should try using sapping points.

2. Fix any bugs.
- squalor bug.
- flashing icons upon building shipwright and higher.
- suicidal generals. AI should value their family members more.
- protectorate bug where player loses vast amounts of cash to protectorate.
- bridge bug where entire units sometimes die upon routing.
- bug where Greek Royal Pikeman don't have long_spear.
- experience gained by auto-resolving battles is greater than when fighting the battles.

3. Don't alter speed.

4. Diplomacy
- selling map information appears to be slightly exploitable.
- it would be nice if alliances and military access might be achievable on higher difficulty levels.
- it would be nice if alliances and the attack factions option would be a more achievable.
- at the moment diplomacy on the very hard difficulty level, other than exploiting cash for map info, seems kind of redundant.
- the cost of Bribing should be proportional to one's income.

5. Ships.
- lessen the amount of ships the AI builds as it's a little excessive and will be a massive drain on their economy.
- AI should attempt to blockade human ports and be more proactive at relieving their own blockaded ports.

6. Increase chance of ambushing and being ambushed. Great feature but under utilised.

7. AI should build assassins.

8. Improve Carthage a little.

9. Move Marian Reforms back a little. Triari are rarely used.

Most of these should be relatively straightforward; nothing involves any major alterations and the majority are bugs or quick fixes.

Hope you listen.
