My alliance are on an AW winning streak - 12 in a row . We expected to lose the last three wars, based on their levels and make-up of their defense teams. Great team work, communication and favourable BOARDS have definitely helped.
The last war in particular, came down to the very last flag. It was the best war yet . I expect the next war will be brutal - we’ve been preparing for defeat for a while. I am still wondering how much of a factor previous wins /losses have on war matching as the top 30 heroes in each roster, number of players etc, can be more easily measured.
