About Shadow Empress and DR

Bishop's hyper seems to be active forever, its like using phantom's final feint. You take a full DR damage and still end up being alive but, if you attack DR again you would die. It's not particularly going to help you at empress unless you attack very very slow. If you bring anyone that attacks too fast or if you're the lowest hp guy, you're going to see yourself dying twice (like literally) because the other guy is going to trigger DR on you too lol.

I've only ever had gate casted on me once and it didn't run out for the whole time i was online. I think it would work fine but a revive is a revive right? When there isn't wheels, i can just bring a bishop in and have two gates available.
