How would you buff the "weakest" civs?

"Weakest" being defined by you. I think the Vietnamese are weak, but you might not.

I'll start.

The Khmer

I believe the Khmer are the overall weakest civ on average.

What they really need is a good eco bonus. And I think I know how to do it.

Two handed-swordsman upgrade, and Cavalier upgrade free

The Saracens

They need buffed, and definitely need a better team bonus.

Team Bonus: Market costs 75 wood.

This is already a bonus of theirs, so why not apply it to the whole team, and then give them a new bonus in it's place... Such as:

Coinage and Banking are free.

Incas

They're pretty strong, so don't need much. Their team bonus is arguably the weakest in the game though... I'd give everyone on the team a free Llama and make the faster building farms unique to the Incas. So a similar treatment to the Saracens.

Vietnamese

The Vietnamese bring much for a team but don't do well on their own. I believe it's because they lack an eco bonus, and their unique unit is none too impressive.

So: I propose that all Eco techs research 50% faster. It makes sense to their history as they were primarily miners and farmers. I'd also make the Rattan Archer cheaper. and give them Husbandry

Portuguese

Buff the Caravel's damage, as it is now it's barely worth making them, but they're already not too expensive either.

I'd also give them Ballistics for free.

Finally, the Portuguese were traders. I'd make Trade Cogs and Trade Carts create 20% Faster

Italians

I love the Italians. They just need a little help.

They were Artists and some of the most brilliant minds of this world were from Italy. For that reason I'd make University techs 25% cheaper I'd also give them Siege Engineers.

Koreans

They do Great in Imperial and on Black Forest. I would buff their early game just slightly, as their only real strategy is tower rushing, and the occasional archer rush. To make them less predictable I would give them Bloodlines.

The Malay

They're in an OK spot. I'd give them Thumb Ring for free

These are all my own opinion. Feel free to contribute/correct me/tell me how OP that would be. I'm curious to see what you guys would change.
