Do something about 49%!!!!
To me at least, there are a lot of cases when I attack somebody and loose with just 49%... when I was just one building away... and I loose -20 trophies or even more. So I figured out a feature that might work. To have some sort of draw if you have at least 40% overall damege. If you have under 40%, starting from 39% overall damege you will steel loose trophies as usual. But if you have at least 40% you don't loose, but you don't win either. Instead, your screen shows that you got 0 trophies. After all in few times the person wich attacks you will loose (Unless he surrenders intentionaly) So this might or might not work depending on what you think, but at least consider doing something to decrease the times what you loos with 49%.
