So pretty much there is not alot of things you can do with clans(guilds/factions) and i think there is supposed to be more
[b]Clan Base[/b]
so what i'm thinking about is maybe they can add a clan base and in the base they can have a duel arena to test out new players or maybe train them or maybe have fun , and maybe there would be some kind of card game in the base and we can use Grimoire Cards since there's no use with them
[b]Clan Recruitment[/b]
So for the recruitment part i think there should be a place in tower where people can Sign up for clans or maybe they can look for the clans that fit them without going on PC/Tablet or whatever
[b]Clan Events[/b]
Maybe there can be some clan events just like the iron banner but in a different way they can have an event maybe like 12v12 or 24v24 or even more , the game mode could be like the normal beta multiplayer mode with 6 flags depending on size of the team or maybe some more different game modes maybe a group with 8 clans and the first to finish the objective like maybe the first to reach 1000 points (this is just an example) wins the event , the people in war can be chosen by an administrator
These are the ideas i have in mind so hopefully something will be helpful
EDIT : if you have any ideas be sure to put them in comments section
