Clan War Matching should take a clans XP level into the match up
My clan has not warred often but when we do we now get matched with a clan with many more wins than us and consequently we get crushed. The match up itself is not an over match, what is over matched is the war experience between the two clans.
It would be great if part of the clan war match up also matched you first with a clan the same level as you. Doing a CW against a clan much more experienced than you is really discouraging to all the members and discourages going to war. Its not the loss that hurts, its the crushing defeat that makes it feel like whats the point? So it would be great if a lvl 1 clan was matched with a lvl 1 clan (all previous match up also into account: number and overall strength). Matching a lvl 1 or 2 with a lvl 9 or 10, even if all else looks even on paper, will be lopsided.
