When Rengar is an ally to Sejuani, he gets a noticable increase in his full damage output. This may indicate that Sejuani helps provide protection for him to dish out more damage or that her presence on the team also helps extend the round's duration.

This is contrasting evidence that he is worse when playing alongside Sejuani.
Moreover, when Rengar plays with Sejuani on the same side, he often takes a little less damage than when he fights alone. Receiving not as much damage could indicate that Sejuani does a decent job of covering Rengar during team fights.
