Alliance War Tier Guide
What is Tier and how to upgrade it?
There are 7 tiers to alliance war maps. They are based on matchmaking power.
Here is how they work:
Right now there are about 20–30k alliances. So, Tier 2 is roughly the top 300–500 alliances or so.
To increase your tier, you just need more total troop power in the alliance. This means either more members or more power per member.
Right now the “mark” for T2 is probably around 85 million total. Although this is a moving target, increasing slowly over the course of the season and then dropping at the start of the season (when tiers reset), as it is based on where every alliance is at.
Whether you want to [increase your tier] is a whole other story. As you climb, alliances do get stronger and more committed to war. So, you might end up with a LOT fewer tiles, which means while the per-tile reward is higher, you might actually end up getting less.
I’d say you should only make the attempt if your alliance is in the top 3 every time in T3 and is 1st about half the time.
