Don't really get the difficulty complaints with the Souls games. You have summons, those are the options to make the game easier. You can summon offline NPCs for a bit of help or just get some help online and let someone basically beat a boss on it's own for you. I understand the complaints for Sekiro, because it lacked summons, but the souls games have those options. I don't think an additional easy mode is needed and I have the feeling some of the complaining people don't even know of those options.
The souls games are also not that hard, once you try them. 100+-percenting Crash 4 was a tougher and more frustrating challenge for me than Bloodborne, Dark Souls 3 and Sekiro. At this point the games have some mythical aura and reputation that makes them seem harder than they are. Don't get me wrong they are challenging games, but you don"t need to be some super amazing hardcore gamer to beat them. I had too much respect for those games too and always wondered if I am good enough to finish those games and now I am easily rushing through NG+++++ in Bloodborne and DLC and most of the games challenges are a cakewalk. Don't have too much respect of those games and try them if you want, there are ton of things to enjoy in those games outside from their challenge and Sekiro aside you can get help if you struggle.
