I want to remind you that the bug that was fixed was that the 1st tick of damage dealt AFTER MISSING by beam was dealing less damage than prescribed. i.e. the bug only made a difference if you were missing plenty, which you wouldn’t be dealing plenty of damage anyways.
What made one of the most situational primary weapons in the game prevalent was how unnerfed double shield comps being played on both sides was the best environment for primary to shine.
The biggest mistake the devs made was infinite tp. it essentially put a guaranteed 12s down time on the hero and did a complete 180 on the sym3.0 rework. Subsequent nerfs were nails to her coffin.
Sym3.0 fundamentally needs a more frequent tp whether for herself or for utility. Jeff himself said he wants OW to be fast paced → no time to bunker down for a static tp. Sym needs the mobility for her effective range. Sym had more skillful combos or strats to pull off with more frequent tps. literally infinite tp with such a horrible cd mechanic just doesn’t make sense.
