Sierra’s Problems and how to fix her.
Sierra is the most broken hero not because of her damage output or her mobility alone; but her mobility and her damage combined. Sierra has gotten nerf to her damage for a tradeoff for a buff to her mobility. Shifting power from one area to another isn’t making her any more balanced, its just applying a very small band aid to the problem and hoping it will work. Her ultimate is honestly the most balanced part of her kit and I am not going to touch it in the fix I would recommend below. Sierra can just run you down or hold a specific high ground thanks to her drone. Her counter is supposed to be if you get hit by tracking shot hide behind hard cover she cant hit you. Problem is is her grenade will be enough to finish you off if you do scurry behind cover and are low. If you do get hit by tracking shot and do run for cover she is rewarded regardless because her clip gets reloaded and it gets infinite ammo for the next three seconds.
To fix Sierra I would remove her major perk “Medi drone” and make it baseline and replace it with a perk called “Locked and Loaded” which is “Tracking shot now fully reloads Helix Rifle and grants 3 seconds of infinite ammo”. This is impactful because it forces Sierra to reload more often when shooting instead of relying on Tracking Shot to reload for her. This also makes her major perk significantly more impactful, either she is forced to reload after tracking shot or have a faster firing speed after hitting and enemy. Another change I would make to Sierra’s drone is it now has 40 health instead of 125 but her minor perk which changes the grapple speed and range to also increase its health to 125.
