I don’t want to waste a bunch of time and I hate reaching the midgame and suddenly finding out my build is completely terrible so now I gotta start over because modern day developers love “friction” which means I don’t get to respec.

I also want to have fun and some classes aren’t fun, but you only figure out which ones are a ton of fun after a couple of hours, hours I’d rather spend doing side quests or exhausting dialogue trees or having fun.

I like winning in a game, I don’t like reading thru skill trees and planning out builds for the future, it stresses me out. I enjoy that someone else has done the work for me so I can focus on the things I find enjoyable. It eliminates choice paralysis.

A lot of games have unfun aspects that people have figured out how to effectively bypass. I have skipped so many poorly designed shopkeeper-minigames due to running a build that allowed me to make a bunch of money or the like and thus skipping some unfun aspect of the game.

I have a tendency to waste a lot of time on inventory management and min-maxxing figuring out what is the “best” by a few percent. This isn’t fun for me, but I can’t stop me from doing it. Finding a build online stops it however.

None of these things impact your experience of the game. However I agree min-maxxing and this approach to having to create “the best” character is prevalent and it influences game design. Games more and more require you run a “good” build to be able to participate in it, which then encourages meta play which then in turn encourages games to require more “good” builds.
My favourite game in a long time was inscription, because it allowed you to do busted combos and make janky cards. I wish more game designers would allow you to be op (without just giving you a “godmode”)
