The biggest 2 issues with me for PC gaming are
1. Cheats - Its far too common on PC to gain an advantage, whether its a plain cheat or optimised fire rate for gun, wall hack or the like. PC gaming is rife with mods.
2. Mouse and keyboard and sitting 1 ft from a gaming monitor with wide FOV does not mix with players on a couch wanting to sit back with a controller.
Yes cheats do exist on Console, but anyone claiming PC games have less issues is a google search away from being proved wrong.
I have always desired PC like performance in a console with controllers in my living room.
I play MP games on PC often, and I don't think cheating is as rife as you think. Rainbow Six Siege had issues with it because Ubisoft released the game without any client side cheat detection, but has since fixed that and the game has been fine since then.
If you are that concerned about cheating I don't know how you would be ok with the way people are using completely undetectable mouse and keyboard adapters on PS4 and XB1 now. That is something that is only going to get worse as more people buy them just to keep up with people they perceive to be using them. They have gotten much more advanced and absolutely do provide an advantage now, and there is no way to detect and ban them since they emulate a controller's signal to the console.
There is also things like the CronusMAX allowing people to create hardware macros that are undetectable as well. Neither console or PC 100% cheat free right now and I don't see that changing anytime soon. The best you can hope for is a good deterrent that turns off 99% of cheaters.
As to your second point I'd agree with that, those are two seperate audiences and it doesn't mix well.Not a lot can be done about that really unless people want to accept new inputs.
Having 2-3 options some of with will be no-brainers depending on your setup is far from having to tweak settings.
And no one is forced to upgrade since games still are going to run on the original hardware.
The floodgates are open though. Tomb Raider will have 3 modes to choose from. Considering all I do when I launch a PC game is maybe turn VSYNC off and that's been overblown by console gamers as 'fiddling with settings for hours' I think that compares.
Also, no one was forced to upgrade before to have games run, either. Now you understand what it's like to have to correct people's assumptions on that matter.
