I'm horrible with Hades. One thing you should always do though is make walls. You can see that making walls are worth while.. Kind of. If you can get them up in time.
The main reason I didn't quit is because I felt a strong sense that my ally would come through for me. If I had a weak ally, then I would have for sure quit. Being teamed is not easy to recover from. Luckily, these guys were stupid and didn't make much of a defense, only an offense on me.
