Hey. Can anyone help me out here and name the most important bosses I should cover, I gave up on trying to beat thebDLC but ai wanna get the most out of it. I've killed...

Black plague Knight
Dancing lion,
Rellana,
Messemer,
Prescendant Knight,
Bayle,
Commander Gaius,
Dragon Sassanex,
Various other dragons,
Dragon man,

I think I missed one but can't be that important. Where should ai head if there are more remberance/side bosses? I feel like I'm missing dungeons with the way people talk about the DLC being loaded with content. Feels empty to me.
