Pro league page rework

Pro leagues are there for over a year now. I don’t think it is necessary to have that big tutorial thumbnail in participation page.

So better move that to upper right and make the icon small like in elite boosts.

And put a description page at the place of current thumbnail which will allow us to know the set up before entering.

Moreover make it more like wars. In war we are able to know what boosts are coming in next war immediately after the current war ends.

We want a same type of feature here :grinning:
