No use telling you anything, you're just annoying forum wannabe troll who's abysmal at the game. You also lack basic intellectual abilities.
DTV is incredibly easy to play when everyone is doing his job. With just 10 players it's easy to get to tincans, but everyone must kill at least few bots per wave which really isn't that hard because they are bots. All it takes are basic blocking skills (like mine, because I'm not very good at blocking) and knowledge of bots behavior.
About shields. I used to have 1 Shield skill and was using Old Heater Shield for a long time (before all these shield buff occured). Rarely if ever got hit by archers. That's because you can point a shield in a direction where projectile is coming from, therefore blocking it. But most don't do that, get hit from above and qq, shields broken.
