There are a few issues with game design I would like to address that I think could improve the game.
1. When at war with a guild, anyone from any group on their claim should be flagged for a period of time so you don't lose alignment for attacking or killing them.
2. Add a 24 hour timer to all join guild and leave guild functions.
Now to explain,
As the game stands now, there are many ways to abuse the alignment system to negatively impact your enemy. For example, imagine being on a raid and your adversary has a player that leaves the guild and keeps running up on the walls drawing archer fire to punish your alignment. Or running into your siege torches or melee attacks. All while being able to keep hitting his bind spot in the base to return.
