Loktionov is a solid two-way player who can fulfill various roles on the team ranging from a defensive expert on shorthanded units to a playmaker on a power-play unit. He sees the ice well and effectively uses his linemates, creating a number of scoring chances. A couple of more significant improvement areas for Loktionov include his faceoff skills and his scoring ability. Specifically in regards to his scoring ability, while always a danger in the offensive zone, Loktionov prefers to pass rather than shoot and in a shot-filled North American style of hockey a more multi-dimensional game would make him more dangerous and hard to contain.
