Cull: In the new series, Dungeoneers will be able to see anyway so I think the hands-on puzzle could be done. Regarding the morality ending, I think any team would do the right thing and rescue the maid - witness that team in series 2 who used FREE on Gretel instead of themselves, despite Treguard advising them otherwise.
Good point about the team using FREE.
But as for your suggestion fo the dungeoneer being able to see... well, sorry for sounding like a skipping 2 Unlimited record, but no, no, no, no, no, no, no, no, no, no, NO! You can't get rid of the whole "Helmet of Justice blindfolding the Dungeoneer" concept  - that's part of what made the team work so vital to the quests success... otherwise, you may as well not bother with the advisors. And then you'd just be watching the dungeoneer wander about the dungeon themself... which sounds to me like Knightmare being dragged down to reality TV levels!
I never was happy about them bringing in things like Insight potions and spells so the dungeoneer could "see " their way round a room - beforehand, good team would be able to guide their dungeoneer perfectly well without help, and poor teams who couldn't were rightly killed off - letting the dungeoneer see is almost a cheat's way out of this in my eyes.
