No, I never got around to beating ??? on hero mode without the almighty ring. Something I've been meaning to do.
Thought about the typeA/typeB argument NJF brought up prior and whether IoR has changed my view on this. It hasn't, in fact its further reinforced it. Decided to elaborate on the "murmurs of discontent" here are some from the IoR review:
"Speaking of difficulty levels, the way in which they were implemented were sub-par" - Orithan, IoR review
"a bit too hard in my opinion" - Joelmacool, IoR review
"This brings me to yet another complaint: The difficulty select options"..."Want to know another complaint I have about difficulty? Differences. The only difference between difficulties is damage, and that's it." - Nexas, IoR review. Liked by 8 people
"A little too hard in my opinion, even on normal mode." - a30502355, IoR review
"Not to mention the insane difficulty curve" - Homura, IoR review Liked by 6 people
"The Ugly: The difficulty. My goodness. This game will make you pull out your hair" - Shoelace, IoR review
"Then there's the friggin' bosses. I admire what you've accomplished Evan but I think you went a little overboard" - Brocknoth, IoR review
"bosses tend to be a bit ridiculous"..."but they are just extremely hard" - Bagel - IoR review
"I switched to "easy" in the later part of the game, not because I couldn't take the fights themselves, but because it allowed me to focus on puzzle solving / path finding" - Jamian, ioR review
"very condescending towards players who may want an easier or a more relaxed experience"..."There are a lot of hard and/or cheap things to dodge in the quest"..."what I'd instead think should be the case is that while enemies are though (sic), once you have learn their patterns you should be able to deal with them while sustaining minimal damage." - Lunaria in the quest design forum.
For the life of me, I can't see it happening - the day when IoR is truly nerfed to suit these criticisms. Evan will only ever make difficult quests and then put in cheap nerfs to suit everyone else. But at least you should draw some comfort from the fact that the challenge quest players out there, few and far between as they are, accept you for who you really are - a very good player who loves challenge coupled with a brilliant, mean, brutal and exceptionally-gifted quest maker.
