Tbf mate, id use the lack of pressure on you to win to complete objectives and get rewards that come with experimenting with rivals.Think it will be Squad Battles only for me this year as my son won 4 placement games to get Div 3 in Rivals. Too good for me that, can’t put up with the stress at that level!! In the meantime I have traded up to 1.4 million coins on the app; since I never pack anything decent before TOTS should ensure I can at least build a good team.
One reason I never do all objectives is cos many require using certain players in rivals & I don't wanna take chance of losing too much & relegated too many times.
If you're not bothered, its ideal opportunity imo
