It doesn't pull brawlers right up to you from max distance. You can pull an Edgar and kill him pretty quickly even with the shield as long as you stay away. But you can also hit 2-3 shots on an Edgar before he kills you which is enough to charge your super back if you've landed a couple shots already
Gray is such like a genuinely solid brawler, So many other brawlers feel janky, sometimes being too powerful or sometimes being way underpowered, grey just feels good to use honestly.
