The whole discussion about "luck" is imo highly laughable because it implies that you can only win this game if you get tons of cool stuff. But that's not true. You can win the game and beat every enemy with almost every half decent item and even if you don't optimize your character to the maximum. I personally quite wasted some ability points. It's really not a big issue. The game gets easier along the way anyway.
Well, I wasn't trying to imply you can only "win" with RNG itemization luck, only that it can cause two players to have very different experiences with how much money there is to be made (and thus how necessary theft feels).
The ease of the game post-Cyseal seems to be a common complaint many have raised, so whether or not things would continue to work well had the difficulty been balanced better remains to be seen.
