Perhaps. If you're questioning an enemy mage, you better tie his hands. You don't want him to Thunderwave/Sleep/whatever everyone who has circled around to question him. There are even Grappler builds that are designed to pin and restrain enemy casters. It's a thing.
I'm playing a Sorcerer in the Encounters sessions and enjoying it. I'm having a good time with the Sorcery Points and metamagic. There was a moment in the game last night when a prisoner escaped from our group and went yelling and screaming to warn his friends. We needed to put him down ASAP...
