As has been pointed out in a couple places in the thread, this deck need more economy. If the runner forces you to rez a large piece of ice on a server, it's most likely going to leave you too broke to rez ice on anything else. If the runner gets out their breaker suite, there's very little in the way of keeping them out of your servers, even with some large ice rezed. They can always just run on everything else. Also, Emergency Shutdown becomes a thing of nightmares. In a deck with this little econ, you can not afford to have to hard rez the same Hadrian's twice. Plus, you need money to kill the runner with. Both SEA Source and Punative Counterstrike rely on traces in order to fire. If you're up against a rich runner who's making you rez everything, chances are you can't get the shot off.
I'm also not sold on Dedicated Response Team in a deck where you can't just tag the runner to shit and back, like you can with Midseason. There's no guarantee that it will ever fire at all. You might get lucky once with the runner running into a Data Raven in the early game and getting a free tag off the trace, but that's just a potential 2 damage somewhere down the line, and since the runner knows you can tag them whenever, they're going to be running with cards in their hand.
Another problem with dedicated Weyland kill decks is that if the runner gets a plascrete out then your entire gameplan kind of goes to shit. An early scored Cleaners can help a LOT with this, since 2 scorches can flatline a runner through a Plascrete and a full hand, but that only works if you've gotten both scorches and a tag method (most likely the SEA source) ready (and have already scored the Cleaners) in a deck without an Atlas to tutor for them.
