Well I asked my friend who is a casual player/semi casual in that way that he does not play often however when he does every week 1-2 times/week he plays 5-7 hours. I play more often however 7 hours feels to much to me.
The only Blizzard game my friend has tried is Diablo 1. My friend is not a MMO player either actually Neverwinter is his first MMO.
Here are the reasons he like Neverwinter:
+ Graphics look nice to him. He like FPS games so yes he knows there are games that look much better. That said he has said it look nice and it is not bad as I have warned him that some people think it is.
+ System requirements... my friend has an old desktop computer with a CPU with 2 cores.
+ My friend is certainly not stupid and he plays his Wizard fairly smart. In Foundry content when I loose my patience when it becomes some annoying puzzle he keep a positive attitude and usually solves the puzzle fast or finds the missing key or hidden door.
+ Action Combat. My friend likes FPS games and Unreal Tournament 2004 is an old classic for us. It is not suprising he likes PvP also in Neverwinter with aiming and fast movement.
+ Dungeons are fun to him.. 45min -1 h? It is nothing to him he prefer to play 5-7 hours when he plays. Dungeons involve fast paced challenging content.
+ My friend likes to play the game with me and we actually prefer to use Team Speak 3 for our internal voice communication.
+ We had very fun in the Orc area when 25+ Orcs chased us... sometimes it is better to retreat then die fighting. He likes even outside world questing.
My friend has seen the LOTR moves and think they are good he even liked the Hobbit movie actually more then me. He knows what Dungeon Dragon is however he does not care much for Dungeons Dragons or roleplaying.
Anyway there you go listed why my friend likes this game and he is NOT a Blizzard or Anet fan neither does interrest him as a company. My friend like Action movies like me however he does not like so much horror content as I do. Lol my 23 year old little sister like very scary horror movies more then my friend. My little sister is a real horror fan she loved Ginger Snaps(2000) when I showed it to her and we watched it with some friends.
If the guy likes the unreal tournament games (personally love them.all.except unreal.tournament 3) then he must be a good judge
I guess Neverwinter caters to.a.certain category, like DDO.
