TL:DR At the bottom if ur lazy lol
Symmetra is obviously a bit of an inbalanced hero, but her accessibility for disabled people is invaluable. However, I think that she has potential to be reworked in a way that would not make her a completely new hero. The new abilities planned should straight up be an entirely new hero, because literally not a scrap of her identity is left. Her gun, while being having no aim, is balanced by being extremely close range, so if someone dies to that, its not that they are OP, it’s that the person is an idiot for being that close anyway and STILL not managing to kill her from close range with her charge up (because lets face it, even a mercy can kill her quickly before she can charge up). Mei is a hero that is similar to Symmetra, she has a lenient weapon that is fairly short range. However, the difference between Mei and Sym’s gun is that Mei’s alt fire is a high skill projectile, while Symmetra’s is a slow Spam projectile. If Symmetra was given a ranged alt fire (Preferably one that can headshot), her skill cap would increase exponentially, and it would balance her kit as she would be able to do more damage without suiciding into the enemy team, like the current design.
Her Turrets aren’t that far off, I would keep their numbers as is, because 3 doesnt lock an area as well. Keep the turret HP Increase (or maybe even make it more, like 60 HP) so at least its a little harder for winston, and let them Pass through Armor. I am not looking forward for all the Armor thats about to be in this meta so I’m just adding this randomly lol.
Her Ultimates are actually fairly balanced, but increasing the range of both turret and tele placement would do worlds of difference for protection.
Photon Barrier is a good way to protect, but it’s on a 10 second cooldown. Lowering it to 7 or 8 would do worlds of difference in a fast paced game like overwatch.
These changes are obviously not going to make Symmetra viable in all comps, there are heros designed to be niche like Mei and Reaper and if they were in every game it would be extremely unfun to play (Ahem ~ Junkrat?) and I think thats fine. However, whats not fine is if she were to be completely ineffective for every other area except her niche, Which I think these changes can do
Keep the planned changes for something else though! It looks really fun, but it doesn’t fit Symmetra really. Make it an entirely new hero, like perhaps another Vishkar agent (Sanjay). But changing everything about Symmetra is simply creating an entirely new hero and destroying all the work you did, and in the end (with all the new animations and textures) the only work you saved was a model (actually probably not because her new gun would need to be updated)
TL:DR - Change her alt fire to something that isnt mindless spam, that way she can do damage without suiciding into the enemy team. Also a couple buffs here and there, and make the planned changes an entirely new hero because it sounds fun to play but is literally everything but sym.
