Hmmh. I think that some spells should have had an extra cost. Tiny hut is a bit too powerful imho.
Yes. 10 minutes is fine. Last night in our Phandelver campaign we came upon a marble double door with strange lettering. My Bladesinger started to read the comprehend languages ritual. Before she could finish two other party members were surprised by wandering stirge. My Bladesinger stopped the ritual to help get the blood suckers off her companions. After killing the stirges, the party did not want to spend any more time waiting so the monk just opened the doors.
DMs can make it hard or easy to cast rituals depending on the situation. It hardly matters how long it takes. And, if it took any longer than 10 minutes, my Bladesinger would never even try to use while adventuring in unknown territory.
