Still, this is MCU, so we don't know if the heroes will use the stones like they did in the comics.

The use of the Power and Mind Stones are only due to unique circumstances involved in the situations they were used in, such as Star-Lord and the Guardians using the Power Stone to stop Ronan and the Vision needing the Mind Stone just to live.
