Yeah, totally lame to actually have control over your roster.
I'm fine with it. Maybe it'll be more work than I expect but at least for one season I am certainly willing to put in the effort. Besides, I like doing this kind of stuff.
This is a joke, right?
To make the winner someone who is more deserving of the win, rather than someone who randomly picked the best squad at the beginning of the season. It's certainly not pointless; it's a pretty big change. It allows people who want to put in more effort for their team to do so.
