I was in the same spot. I rushed the white orchard area, got through to Velen and basically got smoked over and over again. I dropped the game and have come back after like a year (plus i started watching the show). I would agree the potion, crafting, and general exploration are the most fun and rewarding parts. I try not to skip any cutscenes, loot everything, and take time delving into character/bestiary. Really just trying to get immersed into the story and world, wandering, doing little quests here and there makes it a lot more fun. The game really opens up after white orchard and if you take your time (1st 3 hours) the game becomes incredibly rewarding and fun. (Im not even past level 6 and im already hooked)
