The gulf between "
I completed Dark Souls 2 with a spoon" and "I'm really not good at the games and summon for every boss" is massive. Millions of people play these games. It's not just some elite cult sitting in the dark in a basement.
I've got the platinum for all the games, Demons, DS1~3 and I'm pretty good at Souls (edit - Bloodborne platinum too). Killed nearly all the bosses solo. I'm far from the best Souls player, but years and putting hundreds of hours into these games means I'm quite good.
My point? Sekiro appears to drastically change things up, so while in pre-release it was hyped up to be Soulslike, it's apparent in reviews it's not quite. The online and diversity have really gone and what is left might be for some FS/Souls fans, but not for others. That is okay, and that isn't just about elitism and rabid fanboys shouting "git gud". Some of us are pretty good, but the game just isn't for us or will be picked up when cheaper.
As someone who is invested in the Souls community, you're damn right I'm going to kick the beehive when "git gud" changes from a funny meme into the stupid fanboy wars and elitist bullshit rife in gaming. So I will be telling some people to get a grip if they get offended not everyone is drooling over Sekiro/The God Miyazaki.
