Adding such a rematch button to league games would facilitate win trading and essentially cheating the system to give you whatever rank and league you want, devaluating the whole process.
You are free however, to add your opponent from a league match to your friends list and challenge them to an unranked game afterwards, which will not affect anyones ranking.

There are the special units for each team which enable very different strategies. Have you looked at the help section? Every special unit is explained there.
