I've only consistently cleared Advanced levels so I don't have much insight on Extreme, but here's what I know.

It'd be difficult for new players to progress as quickly as experienced players because they'd have the decks required to do Advanced/Extreme modes that give more "Floor Passes" than the easier ones. Also, based on what I've seen, Advanced/Extreme rune bosses seem to be able to give multiple runes per fight which can allow those players to enter Rune Time much faster. In Rune Time, you basically earn at least 10x more Floor Passes, allowing the player to advance through floors more quickly.

Rune Bosses are very difficult. An Advanced Rune Boss has 100m health IIRC and can compare to a LAW - granted you have 3 teams to take it on but their Crits and Waves will kill any kind of non-GUR+ card easily.

Alliances/Comrades don't matter.

No idea yet as to how the elements of the opponents change.
