It has been pretty common that I'm in menus, or gathering or whatever hitting the confirm button and DF pops and i hit confirm by accident instead. I've been running up to a hunt mob, hit X to select the mob, and boom I'm in a dungeon instead of waiting 20 sec for the hunt to die. Same with fates. I've actually missed a relic book fate this way. There are lots of times you hit the X button alone to navigate menus, activities that don't involve the safety of the shoulder button and duty pops have a nasty tendency to pop up during those times.

Fully support the new wait feature. It's awesome.
