I can confirm I have never won against someone that surprised me. In the Russia WD, all my wins were against people I should of won against. But my losses were split in two categories - losses I deserved to lose and losses I should've won (like Attack exceeding defense by 30%, army equipment exceeding by 15%, and soldier equipment tied). Sent a ticket and, you guessed it, got an unhelpful response "ticket closed"
And what's with Double strike causing a loss to a player I've hit normally 20 times and won every time then a double strike comes and I lose? I would of sent a ticket on this issue too, but we all know how pointless that is.
