i think the problem people have with rituals is that they're not the "instant speed i win" buttons magic used to be.

the knock ritual is for when your rogue isn't around and you don't want to "BANG KLANG CLUNK BOOM CRASH" your way through a door. mostly because the noise will alert enemies. and 10 minutes really isn't that long, 2 short rests.

true, they're not the old 6-second problem solver, but they're not supposed to be.

some could have been made less lenghty, but magic is no longer the be-all-end-all in 4th ed. it's a new paradigm.
