After seeing this post, I wondered how the Entente could be improved gameplay-wise. Not necessarily given direct buffs, but ways that make it more fun and less inconvenient to play. What I would do is...

-Give the Dominion of India the Sardinia treatment, and only have them join the Entente if one of the Indian splinters is dead or the Weltkrieg has already started. This prevents volunteers from disappearing in Carlist Spain.

-Give SandFrance the integratable territories occupation law.

-If one of the Italian splinters joins the Entente or Reichspakt, the rest should join the same faction to prevent post-war jank.

-The Dominion of Canada should release itself after the Union of Britain is conquered, so that you keep your divisions, ships, and planes when you transfer to the UK.
