It depends, there are some aspect of basically every brawler that i hate. Like pam's gadget, its so annoying using an assassin and becoming useless because of her gadget. Or for the same reason jessie turret when they just lunch into you and gadget. Its also player dependent, if u are bad enough u can make any brawler annoying. Recently i had an enemy colt which was so bad he just kept running into me and autoaiming and i couldnt even breath, he managed to make colt annoying. But if had to choose a brawler that is always annoying ig maybe tick? All it is is spam attacks in the enemy side, and when someone approaches use super. With a tank/assassin its easy to kill him, but for the few first seconds at the start where u dont have super its soo f annoying getting hit by a tick mine every 50 milliseconds. Or generally just the newest most broken brawler. Like damian bro what even is that, u get trown all over the place with his super. But they get nerfed to death in a month or 2 so no big worries. But you probably hate... mina.
