Just a look at the new League Table Tabular format gave a weird feeling 
The old Group Stage format gave a more bigger tournament feel of the likes of World Cup etc. 
Agree with @Lokesh regarding Widening Wealth Gap, Player Fatigue and Commercialization over Tradition concerns. Wealthier clubs are expected to benefit significantly from increased match revenues and prize money, allowing them to invest further in their squads and facilities. While mid-tier clubs might struggle to compete with wealthier teams that can afford better players and facilities. This could lead to a more pronounced competitive imbalance across leagues.
