Walls seem to be too big a factor in War matching

We've had a few wars where we were matched quickly but pitted against way higher THs and the big difference seemed that they had only pink and purple walls. In one now with 7 th9$ to our 4 in a 15 min search. If that's what it is, then it's outta proportion considering all the ways to and troops which make walls irrelevant. Anyone else notice this, and supercell, if your out there, seems that it would make sense to ignore walls for matching, or greatly reduce their weight so it can't be gamed this way.
