So this idea might sound a bit strange, but when you approach an instance, There should be an oval shaped spot that glows. If you enter the oval, you are automatically entered into team up! If another pirate is standing in the oval shape, different realm or same realm, both pirates are asked to accept entry together. I feel by doing this, the rate of team ups would greatly increase. To go with that, if you leave the oval shape, a notice will appear if you still want to wait for team up, so one can still wander around while waiting. If you do not want to perform team up, you can still enter the normal way, while knowing if there are other pirates waiting at the same time. I hope you all understand what I am trying to say! Also, I chose an oval shape because if it were a circle, pirates might step into it more by accident and be obstructed for a second.
