Opt in is NOT in war
Opt in did onöy count for upcomming battle, so it could happen that you have 50 opt in but less than 10 in actual guildwar.
I think there should be a 3rd status:
I sometimes think, we have still 1-2 peeps that didnt hit yet bit they are NOT IN BATTLE, they are inly opt in.
Also it could someone hit and than opt himself out and is now opt out evem when he partizipated in battle....
