I didn't find difficulty to be a problem usually. My problem is there were just way too many enemies. I wasn't playing this game to fight wave after wave of speedbumps, I wanted to invest in the story and world. That was hard to do where every encounter would take 10 minutes. To top it off there were some flat out ridiculous events, Ser Cathurien being one. Hmm walking into an ambush, no prep time, and outnumbered 4-1. Oh to top it off, big boss, can one hit my mages, and shrugs off all status effects instantly.That's not tactical, that's ridiculous.
The Deep Roads were a dull slog through endless waves of enemies. As it stands on normal it was an 80 hour game (I did alot of side quests) that would have been better if it had taken me 50-60 hours. The world and it's factions aren't bad, but there just isn't enough interesting decisions to make it worth that much time. Forget doing multiple playthroughs. I've started a second game, but did so on easy. I want to enjoy the story at a faster pace. I liked having to be careful with combat, but it simply takes too long.
For a game that seems to encourage multiple playthroughs the combat takes too long. I don't want easier combat, just less pointless filler fights.
