In theory you should reach 100-200% of your old rank. You should still get rank 3 since some of the requirements may go down slightly. If you were a barely 3 alliance, you will prob stay at 3. If you were a mid 3 alliance, you should get closer to 4. If you were an almost 4 alliance, you should see 4, perhaps 5. 6 could be possible but I’m thinking they arent lowering the missions that much.
