Apparently there was a bug recently which transferred Honour Mode legendary actions to non-honour mode saves. This is something I've been desperately wanting for a very long time. I started my save on Custom Mode with all the difficulty settings maxed out, expecting it to be the same experience as Honour Mode, but without the permadeath mechanic. I wasn't aware at the time that you can continue an Honour Mode save after dying, or that Honour Mode had extra difficult bosses with legendary actions that were unavailable in Custom Mode. I'm 300 hours into my save, at the start of Act 3, and I've avoided leveling up my characters for most of the game because it's just too easy. It really takes the enjoyment out of boss fights when I know I'm not actually fighting them at their full strength.
Clearly there's an easy way to make it so Honour Mode legendary actions are activated in existing saves, so I'm really hoping it will be added as a toggle-able option in the difficulty settings. Especially because it recently was added to the options when starting a new Custom Mode save.
I'm new to these forums so I'd also like to ask people here whether any of the devs read the suggestions posted here, or is it just farting into the wind?
