Yeah, it's difficult keeping Eye up 100%. If I'm doing dungeons, I'm generally doing Butchers(just at the start)/Eye/Butchers/Butchers. Those 2 butchers will give you about 3~4 seconds of relay until your eye will overlap, which makes it difficult to reapply if you're also using Inner (or the bad luck of being pacified).

I've come to the conclusion that if a Ninja is overlapping my Eye, I'll use path instead. Everyone wins, I guess :<
