Nope. in the og days all premium point did was give you your premium account, so people bought that and skill took care of the rest. now you have people skyrocketing to the tops of worlds using pp. not sure when the change took place, i quit the game for years before coming back ~90 to dip my toes back in the water and it was how it is now.
whether its pay to win or not really depends on how you look at it. its undeniable that pp use gives you an extreme advantage in the early game, but its only going to carry you to the win if you were skilled enough to get there easily. the heaviest pp usage will always be in the early game to get a leg up on your opponents. but with so many people using it, by the time any world gets to the mid-end game, any serious contenders for the win are going to have a pretty heavy pp usage on average, so it more separates a world into two types of players than anything else and that hurts casual players.
unfortunately its part of the game now, and its highly unlikely that thats going to change, Inno make too much money off it. just got to get on board with the idea that this game is now pay to win to a certain degree.
that said you can spend all the money you like, if you havent got the right tribe behind you with the right skill level to back up their wallets then you have as much chance of winning the world as a mass invite tribe with no previous game experience.
