Clicking all buttons

As the header say I play this game clicking all my abilities and just use my keyboard for moving around. I’ve been playing for several years now, taking long breaks in between and for some reason my brain just can’t handle remembering key binds so I don’t mess with it. The hardest content I’ve been able to clear is just savage raids back in like, SHB days. I was wondering if it’s possible to try to do harder content while playing like this or would I absolutely need to have key binds.

Also I never played on consoles so idk how to use the controllers.
