I'll echo what people many people above have said re: most rituals having good utility but at the cost of time. I absolutely hated 3e's magic 6 second solution to nearly every problem. That said:
I wish there were more rituals like cure disease - big effect but with a big and potentially dangerous cost to the recipient (I personally love the fact that the ritual is essentially magic chemo: it might cure you, or it might kill you faster than the disease you are trying to cure).
I'm also toying with the idea of speeding up rituals at the cost of healing surges. So for example Knock takes 10 minutes - 2 healing surges let you do it in 1 minute and 4 healing surges let you do it in 1 round -If the ritual takes an hour it would take 6 healing surges to do it in 1 round. This would seem to simulate the fatigue mages feel for power expenditure perfectly.
