Is it worth doing? I did Hybrid Leagues last night (one of them) and got a Mega Pack. I think I'll do the other 3 but it's a lot of work and are the rewards worth it? My mega pack had an 85 and 84 and a TOTW player which I guess isn't too bad. I get a Mega Rare Pack if I complete all four.
The LIve SBC are way out of my reach (trading an 85/86/87 team)
