So I capped out at 80 friends. Could I get another 80 friends to send me invites? I clear my tavern as soon as possible and check for open seats 3-5 times a day. I also aid every day, with very few exceptions. Thanks for your help!
I don't play on Xyr, but here's my tip on getting the other 60 friends so you have a full list of 140 friends.
Go to your friends' or guildmates' taverns, and send a message to people sitting in the tavern asking if they could send an invite to you. Then, click on one of those people sitting in the taverns and visit that tavern. Send messages to everybody in that tavern. Rinse and repeat until you get 60 more people on your list.
