Mate.I am finding it incredibly hard on classic, just escaped the fort but don't feel like my character is at a high enough level I keep getting hammered.
Stick at it. Honestly best game story wise and RPG wise I've ever played.
Also couch co-op so me and the gf have completed it about 3 times at this point - brilliant game altogether. We're at a point where we've got about 400 hours or so stuck in it (and 130 or so in the first one) and we keep going back to it and having new ideas of how to play and stuff. Replayability is through the roof, as well as the guys who make it being utter RPG nerds (and very community driven - still getting updates, some/most of the "official" mods and free DLC are community-made)... Honestly can't wait for Baldur's Gate 3.
Game of the Year, every year*. Prove me wrong.
* Until Baldur's Gate 3 comes out.
