I am not sure if this is still possible or already got changed.
If it got changed already, close this ticket.
I am talking about multiple players hitting a single wall in parallel.
I got hit like this around a month ago and it felt quite unfair.
Example: you have 50 garrison troops and each fight 10 play (fake numbers to keep it simple).
Now 10 players hit you within 90 seconds.
The first player gets the first 10 troops (which get locked, since it is not clear yet who survives).
Players 1-5 get 10 troops to fight.
Players 5+ hit an empty wall, although there will be defense troops left.
I think it would be more fair, if a single wall could not be hit in parallel.
Assuming a castle has just 1 gate, the attackers need to leave first or die, to make room for the next army
