I would like to know your where you get your data to support "BIG chunk".
To the second point, that is actually just incorrect. You always go TWO ranks down from one season to the other as even stated on the official page for Feast: https://na.finalfantasyxiv.com/lodes...sden/thefeast/
It's more for matchmaking purposes so a fresh player in unranked doesn't get absolutely destroyed by the vets of the previous season and actually have a chance to learn before fighting people of that skill level.
