Feel free to specify where I did that. Quoting my entire post and responding with 4 non-sensical sentences is lazy. I said the event should give a claim rather than a core in a previous post. That response you quoted was targeted at a claim that it was an inappropriate event as it was targeted at firing "hundreds of years into the game" when in fact the situation it is trying to replicate happened within one hundred years. I didn't say they should just get the land dude.
Post I quoted was not the one discussing the claim, but rather that the Portuguese conquest of Goa was somehow a foregone conclusion while westernization (as the game represents it, a costly transition to practices that makes future teching less expensive) isn't plausible, that they'd be able to take this territory in alternative history even if the situation in India and for Portugal were different.
Claim or core, this territory should never fall into Portuguese hands unless Portugal declares war with coring range and takes it.
