Reasons are they want to “nerf” Tubarao (as if they didn’t had enough time by now) and fix bugs on the new map.
Also, Athieno said around 8 hours ago that season was delayed until next week, so this pretty much confirms it is indeed getting delayed

Not that a delay is impossible because yeah, you never know so yes it could be true but atm, the only people who haven’t confirmed or even mentioned a delay are the people who actually developed & maintain the game. So maybe jus wait on word from Ubi
