In our current war we are facing a team of five players. One of these players after matchmaking quit their team and joined our team hung out for five hours. Left and rejoined his original team and is currently on the field. How us this possible?
Quite easily possible. Nothing in the game prevents that. As long as you are a part of your alliance when matchmaking is happening, and back in time for war, there is no issue. Be careful who you let in and when.
We had that happen once before. Seems people think it’s some type of advantage to look at your battlefield before the war… See what color tanks you have… I personally don’t get it, but found it annoying when it happened. We started changing our alliance to Invite only shortly before matchmaking starts and not letting anyone in until the war started.
