And that's the good thing about RPGs:

"Okay, we wait for thirty minutes" takes all of five seconds to say, but makes all the difference in the game.
The trick is to not get stuck in the ''fast casting is only for combat spells''. Lots of spells should be able to be cast without taking minutes and hours. Like most divination detection type spells. A spellcaster walks into a room and can detect undead in one round, but it becomes more useless if they must wait 30 minutes. The same way a spellcaster should be able to make an illusion of a door in one round, and not take an hour.

The quicker casting times for high level is a good idea, but don't just make casting times level based. They should be like ''the normal spell takes an hour, but you can cast the fast version with a check'', then higher levels could do it more often/easier...but any spellcaster of any level could at least try.

Circumstance Bonus: I have always liked the idea of randomness. It's something that 3x can really use. How about instead of a static DC, the DM rolls a 1d10 with 1-5 a bonus and 6-10 a penalty.
