-Hello, how is it going?
Well, this is a modpack for a server but if you want you can download it and play it normal.
-Features: Dragons (Yay!!), Better villages and stronghole, More blocks, better armory, 2 more ores (gronkle iron and diorite), Medieval stuff like armors, mini lore (dragon hunters boats), and more biomes
-How those features affect a user's experience?: Well, it depends in your PC and how is it optimized thanks to the new world generation could work different and because there are more mobs (dragons) your PC could lag.
