I was mainly plugging the indicator light idea. In the last week or so alone I have had at least 3-4 times, when we are sitting at a location near a tower and my self of other guild members will send out gc messages or pms telling somebody to come and meet up with the group.
Then after 10-15 minutes they message back sorry was afk,or you say screw it and attack and after waiting 10 mins for that one person to show up you attack anyways and 1-3 ppl have went afk themselves waiting on that person to show up making it that much harder to take the tower.
