Analysis[]
If a player has been doing the minimum required to get a mission tier's new formation (if needed) and move on to the next mission, Knights will have a short but very useful lifespan in your active force. Because of their high drop rate in the Storming the Beach mission, it is usually pretty easy to gain quite a few of these infantry units. As such, using quite a few of these in your active force will often prove devastating to your opponents because of the high proc rate, more so if you have acquired Boris.
Knights should be replaced in all force layouts as soon as you have superior assault units from War Chip collections, in-game collections acquired with various tokens (including Arena), or other mission tiers.
