Not necessarily, You still need a very strong team like mine to win the shark tournaments at the very least, On the Capelli server and at the very top there is a guy that has 22 players at all 9* every season and wins everything now we are lucky in a way that there was no such team this strong on the July Fourth server. If I don't have the tokens to invest in seasons where my players lose a star my team will still decline quite steadily.
For the last 6 months or so July Fourth has been the dominant team on our server and there is no need for us to carry on investing just to keep winning the same trophies season after season. We have our history now and we can play light!
