Arrow - if you are getting this many bad matches, it's worth looking at your war line up.

From what I can see, you generally War with 4 TH10's, 3x TH9's, then an 8, a 7, and a th6.
For a small war, this is quite a wide spread of town hall levels, and it makes it tough for the matchmaker to find someone with the same line up as you.
Most wars seem pretty close also (penultimate war was lost on % only?)
Try warring with a narrow spread (3x TH levels at most) and see if you get better matches.
