Reyna is overpowered, and has nothing else. she is a full frontal play style that lacks the inexpensive playstyle of jett (with her ult, and general life saving abilities), or the round the corner brutality of raze. for however overpowered Reyna is, she is still forced to confront her opponent directly. flashbangs may be more than smoke, but flashbangs still are not grenades. she's not so special.
