Obtaining it never means having to scan anything at any time.
That's true, it's obtained from gifting.
But what I mean is that there are enough players there to be significant part of the ecosystem. The war made obtaining those Vivillion harder.
I don't understand how it's related.
I am a daily player, I have scanned something once, the rewards were minuscule, I never did it again. I have that specific vivillon which was hard to get because not many players were from the relevant area even before the current events, and I just can't see how the war is related to any of this.
