I think that the normal matches (not pro battles) are too short. Why are they? So I thought that a match could be minimum 10 minutes, it is not too short and not too long. My main problem with the short ones that 1 minute is adapting to the matches ( changes the paint and protections), and personally I like the long matches because you can adapt to your new teammates so you will work together better. Of course if you will lenghten the time you should increase the maximum stuffs like flags, captured points... And sorry for my English but I hope I was clear.
