This is a beautiful DLC. It's almost like a whole new game, not as big as the original but you get plenty for your money. There are some really cool new weapons and ashes of war to find and try as well. But...
They took everything from the last 1/3 of the original game that feels pretty cheap (to me) and turned it up to level 10 for this DLC. I've played through the original game three or four times and probably will again. It's so good and my first FromSoft game. I'll beat this and probably won't touch it again. It's just not that enjoyable (to me). Enemies have way too much health, I mean way too much.
Bosses are hyper aggressive. That makes the camera problems the original game suffers from even worse since you're pressed up against walls you can't see much of the time as the boss rushes you down.
Scadutree fragments don't do a whole lot. I feel like everyone liked ER because it gave you some choice in how to play. This DLC doesn't. You just have to feel weak the entire time. For old school FromSoft fans I guess this was a complaint about the base game. It allowed us casual fans to enjoy the game too. We can't have that in video games of today.
