There is still stronger beast to come like usual, as it is business model of this game. As time passes we have bored whales who are tired of compete with other whales throwing out big money or they are so rich that they can´t find enough challenge for them so they quit. And on the other side there is many f2p players who gave up chasing whales. f2p will never be happy until they realize they must be losing side ( not entirely true as you powering up and are stronger then new server guys). Best they can do is realize that they don ´t need to be top 10 and no reason for chasing that rank, just being patient and enjoying better aspects of the game. There is always stronger ninjas to come and bigger rewards to come as this is business model which seems to be working apart from that many players quit (still enough players incoming) . Not native english speaker but I think people understood and we all perceive it very similarly.
