I didn't play Eco Draconis, as I knew they were releasing expansion packs so i held back for a long time and finally decided i would purchased DKS to experience the whole thing all at once. So for me I don't know what the original game was like before this update. So for me it's all new and never seen before. 4 hrs into the game, I have had ZERO issues, i am enjoying the variety in the quests and the game runs super smooth on my PC (though the graphics aren't anything amazing, but they're good enough). No issues here. Also the game has an antialiasing option. (For the poster on page 1).
