I'm also going to add there needs to be a section on the app to list what region your clan is in, and then region locks clan wars.. obviously this would only work if there was enough clans in a region and im sure when someone makes it possible for everyone to use the app there will be more
having clans from around the world in one clan war again this goes back to the issues i have with scoring is causing issues .
Example our clan (euor based) last night spent ages taking back a whole heap of nodes to catch up with the top team , we get on this morning and bam everything we took was taken back by the top clan (who are in the us) and played after us.
Now before some smart ass says well that works in your favour now as you can take them back during the day ... yes assuming none of us worked during the day and it also gives us an advantage when the op finishes as we can take nodes when the other clan is sleeping.
