Ideas for new units

Hi to all, i played aoe 1 since my childhood and i see that some units need upgrades especially in the iron age, so the possible new units would be:

• Armored Camel: upgrade to the camel rider is neccesary because camel riders are ridicously useless in iron age (expect for cartaginians and palmyrians) since armored elephants and cataphracts are arguably stronger than it, the armored camel would had better attack vs any mounted unit to a more easy way to defeat cataphracts in one to one combat.
• Elite Slinger: Same with camel riders, horse archers and minoan compsite bowmans have more advantages against by their speed and range.
• Armored Elephant Archer: war elephants have an upgrade but elephant archer dont have, so very unbalanced judging that they have strong offensive chances.
• Scythed Chariot Archer: Same reasons like elephant archers.
• Ram: During the antiquity, the rams played an important role in the siege like the medieval era.
• Javelin or Peltast: We have slingers and normal archers, but javelins are relevant during the aoe 1 timeframe (in RTW most of the factions have javelins), their damage would be against academy units.
• Earth Traders (To make Trade Workshop a useful building): Much like trade cogs in sea.

these are mi ideas, what new civs you propose?
