That's exactly what I don't like about it. The game rewards you too much for just fragging for yourself, when that should just be one portion of the game. Reyna offers nothing but kills, her flash is not good for team pushes and she has no space making ability. You can just spam Reyna and rank up for free and not actually get better at the game, which is dumb to me. Locking Reyna and going 19-16 is more rewarded than say, locking sova and going 11-14 but you dart/drone get info and make good comms/call rotates etc.
Plus locking Reyna and just holding angles and wide swinging gets boring after a while, at least to me.
