In addition to friend list ideas
i believe clan interactions should be much more available, mainly for purposes of feeder clans and sister clans
how this would work would be a different tab specifically for talking to other clans that you have added to this list, and you can invite other clans to discussions as well (ones in the alliance tab as ill call it)
why? i believe the having to hop around clans to talk to others is ridiculous and more trouble than its worth, especially since i do have friends that have their own clan but want to be able to interact without leaving (as they won't leave), and yes friend tab would help with this, but i feel you should be able to have at least 5 ally clans, this leaves room for a feeder and sister, and 3 other clans you can communicate with, however the leaders and co leaders decide to set it up, but im sure ideally around 10 would be perfect, this would not affect anything other than communication with other clans, you can still potentially find these clans in war and in raids, (even tho the odds are still low)
yes the friend list idea is great, but it only does so much for clan interactions, however i DO still believe a friend list should be added as well for COMMUNICATION not just having my facebook friends displayed, and these friends would be in a different section than facebook friends but facebook friends can be added to it and alternatively you CAN add people to facebook but thats half of what i mean, if i want to interact i dont want to put out my personal apps and accounts to just talk to people on COC, although people will say LINE or Kik is an option, and it is, its not very fun to flip out of the game to do that. although external communications CAN be helpful, i believe its not the best resource for basic communications, external communication to me should be for more important discussions and things that you dont want buried (since clan chat is so small)
any tweaks or comments, feel free, i might edit your ideas in and i might change this up
