The game has p2w for sure. However, you can get all the resources from different islands. There is no reason for you to rush at all unless you want to join the end game contents faster (Which is unnecessary) You will eventually end up playing those contents.
While I was playing in Korean server, Smile gate actually gave free Jumping characters (Item level up to 1415) for new and existent players to experience part of end contents raid.
I believe there is a possibility of support to help low tier players to experience end content as well for NA EU server. So you don’t have to rush or spend money at all. Just keep your phase and enjoy the game.
