The EP temperament of my dual is very frustrating. The most characteristic "bad trait" of the EP temperament is flakiness, they always give off this impression of having some other place to be, other people to see, and a lot of the times it's not even true - they just want to keep you puzzling over how to make them stay. I rank EP last for commitment and reliability.
Compared to Exxps, my LSI partner was much more difficult to start a relationship with. But after that, he never, ever, balked at commitment. I look at him, and I want him to be the father of my kids, I want to grow old with him. Because he has all the Ti and Se I could want, but also because he will be there.
But I haven't really answered your question of why activity is better than duality, have I?
