I fail to see why it's so important to dictate what other people want to do in a video game, just because you don't like it.
Don't like it? Don't use it. Make it a challenge to complete the game with only mundane items and class features. *shrugs*
I know I'd hate it if I had to give up most of my gear just to make someone that's better at the game than I am happy.
Because, and it is obvious when you think about it, for games being good the challenge in them must be carefully calibrated for the best experience.
Having OP items makes this impossible as how do you now plan future challanges? Based on people having and using the OP items or not.
And just telling people to not use stuff is a very bad thing (again, very obvious) as you now lock people out of content because they are "too good".
That response is idiotic. Calibrated for the best experience of who? If Larian add Attunement then how is the game calibrated for the best experience of me or anyone else who doesn't want Attunement.
As has been stated ad nauseum, all people like you need to do is either not use the OP gear or use mods. You say "telling people to not use stuff is a very bad thing (again, very obvious)" but you telling people they must have Attunement is somehow not a very bad thing? And how your position is "very obvious" to anyone with an ounce of sense is beyond me.
I'm not particularly interesting in making my game more difficult but I'll bet it already is more difficult than yours. I use mods to make things more in line with 5e rules so there are no 5 attacks per round for me; no weapon attack spells such as cleave and the rest; using Spiritual Weapon uses a bonus action each round; no 'until long rest' buffs; etc, etc. Given the currently available mos my game is calibrated for the best experience for me but because I'm not an idiot I am not asking Larian or anyone else to make the game only playable the way I like it.
