Dutch South Africa is broken (in treaty)

Unfortunately a loss in a 2v3; I should have taken advanced arsenal for my hussars but anyway onto the story!

Dutch SA is busted and here's why.

1. You get a 3rd Factory - cancelling out the 2 banks you get in Imperial.
2. You get 30 Courier de bois with the Huguenots Card. I don't think much needs to be said how that cancels out anything you get from Imperial.
3. The 10% gather rate you get also helps null anything lost with Imp Upgrades
4. You get the Infinite Stacking Wanderlust Card which provides 5% unit HP everytime, along with settler health AND speed up 5% everytime from base.

The end result is me slinging 500hp Ruyters and 1100hp Hussars into Musketeers and Longbows for days and then sending a meme force of villagers down the trade route to build without a blessed damn. Also villager HPs were 450 at the end of game along with 10.60 speed so cav was no concern.
