I will never understand this shit, it's ok to DARK SOULS to be difficult, but when other games are difficult, they are complaning all the fucking time, this is absurd.
Dark Souls is not difficult in the same way as D:OS2.
Souls games always give you options if you can't beat a particular boss. There are usually NPCs that you can summon to help you, or you can summon other players, which makes boss fights considerably easier. Even if you don't resort to summoning, you can always increase your stats by grinding more souls/blood echoes, which are for all intents and purposes an infinite resource. The game never stops you from progressing.
In Divinity: Original Sin 2, however, it is entirely possible, as a result of poor stat distribution, skill choices and lack of synergy, to end up in a state where a fight becomes practically impossible, without any means of making it easier or grinding for more xp, at which point your only option is to restart the game. The free respec option does alleviate this, but you don't gain access to it until act 2, which can be a good 20+ hours into the game.
TL;DR Comparing Divinity: Original Sin 2's difficulty to Dark Souls is intellectually lazy whataboutism.
