War Rating Should Erode If an Alliance Doesn't Do 2 Wars in a Week
There needs to be a way for war rating to erode for inactivity now that AW season was introduced in which points are based on your War Rating tier and the top 3 tiers have more limited spots.
I would recommend war rating decreases by 120 - 140 per week in which an alliance did not participate in 2 wars. 2 wars makes up for any match making lag causing you to miss a war during a week. This drop would be roughly equal to if they did 2 wars and lost them both and allows their war rating to stop distorting some tiers (e.g. currently a few are preventing Active alliances from getting x8 multiplier as I counted several top 50 war rating alliances who didn't look to even do a single war since AW season started). The decrease is still at a slow enough pace that if an alliance had a major breakup they can take a couple weeks to focus on rebuilding without falling too far behind on rating.
