Well really everything is OP if you take it to a biological level. If you can apply and remove heat to a single part of the body you can easily kill someone. Air lets you remove oxygen from someone's lungs. Lighting can make a bolt inside somebody's body or mere milliseconds from hitting them. Light allows you to permanently blind someone with ease. Anything is overpowered with proper usage. I assume the GM is assuming we will use our powers in a far more simple light.

yeah, that kind of stuff is "grandmaster" level of magic, and there would only be a few people in the world (like Atmar before he died) that can do it.  The same is true for interchanging light & fire or dark & cold.

We're just starting, so we're more at the "human flashlight" (light), "matchstick" (fire), or "recover from a hangover in minutes" (life) level of magic once we finish our basic training.
